In brief
Hybrid work means that Tuesdays and Thursdays are consistently the busiest days in the office, with occupancy peaks of up to 60%. This has direct implications for your coffee supply: machine capacity, inventory planning, and service frequency must adapt to these fluctuations in occupancy.
- On Tuesdays, the average occupancy rate is 33%; on Thursdays, 31%; and on Fridays, just 18%.
- The average office worker drinks two to four cups of coffee per workday.
- Calculate machine capacity based on your busiest day, not the weekly average.
- Schedule restocking for Monday afternoons and Wednesday afternoons to stay ahead of peak days.
Hybrid work has established a consistent pattern: Tuesdays and Thursdays are consistently the busiest days in the office, while Wednesdays and especially Fridays remain quiet. This difference directly impacts peak demand for office coffee services. Machines that get overloaded on Tuesdays sit idle on Fridays. Below, you’ll learn how, as a facility manager, you can align coffee capacity, inventory, and service frequency with these uneven occupancy patterns, using concrete rules of thumb that you can apply right away.
Why do Tuesday and Thursday consistently see peaks?
Occupancy data from Beyond Eyes (a platform that measures workplace occupancy using sensors), collected from over 12,000 workstations in the Netherlands, reveals the pattern: Tuesday averages 33% occupancy, Thursday 31%, while Friday hovers at 18%. Employees who come to the office one or two days a week almost automatically choose Tuesday and Thursday. That’s when most colleagues are there, and when meetings and consultations take place.
A study by the CfPB (Centre for People and Buildings, a knowledge center for work environments) confirms this “camel effect”: those who work part-time in the office concentrate their presence on those two days. At peak times, 50 to 60% of employees are present at the same time. This concentration has direct consequences for any facility that operates based on volume, and coffee tops that list.
This pattern applies primarily to office environments. In healthcare and logistics, working from home is hardly possible, which means that occupancy is distributed much more evenly throughout the week. A hospital or distribution center has similar daily consumption, which simplifies coffee capacity planning: you size based on a constant level rather than peaks. If you work in such a sector, you don’t have to worry as much about daily fluctuations.
The bottlenecks: capacity, inventory, and service
The average office worker drinks two to four cups of coffee per workday. On a Tuesday with 60% staff presence, consumption doubles compared to a Friday with 20% staff presence. This results in three specific challenges.
Machine capacity. Professional fully automatic machines (coffee machines that perform the entire brewing process automatically, from grinding to dispensing) typically handle 80 to 150 cups per day. The peak times coincide: the morning rush between 8:30 and 9:30 a.m., and immediately after lunch around 1:00 p.m. A machine set to a weekly average will be overwhelmed on Tuesdays. Rule of thumb: calculate your required capacity based on your busiest day, not the weekly average. If you exceed 75% of daily capacity on peak days, a second machine is worth considering.
Stock. Beans and milk run out faster on peak days. If you base your stock levels on weekly averages, you’ll find yourself with an empty milk tank on Tuesday. Restock on Monday evening or Tuesday morning, and do the same for Wednesday heading into Thursday. Use 1.5 times the average daily consumption as your stock level for Tuesday and Thursday.
Service frequency. With heavy use, maintenance may be required every six to eight weeks; with lighter use, once every three months. However, if that workload is concentrated on two out of five workdays, parts wear unevenly. A brewing unit (the mechanical heart of the machine that presses and extracts coffee) that experiences “average” annual usage may require maintenance sooner during peak periods.
Align service contracts with Tuesday-Thursday staffing levels
A fixed-term service contract with a set maintenance schedule does not account for peaks in demand. Ask your supplier for a flexible contract that links service visits to actual usage. Specifically: schedule preventive maintenance for the week following a series of peak days, rather than on a fixed calendar date.
In addition, schedule an internal check once per half-day. Have someone check the bean supply and milk level on Tuesday and Thursday mornings. This will prevent a machine from breaking down in the middle of the morning rush.
Combine this with a clear agreement on response times. An outage on Friday afternoon can wait until Monday. An outage on Tuesday morning immediately affects productivity and job satisfaction. Make sure your SLA (Service Level Agreement, the agreements with your supplier regarding response and resolution times) takes this into account.
Example: an office with 200 flexible workstations
A facilities team manages an office with 200 flexible workstations. On Tuesdays and Thursdays, an average of 120 employees are present; on Fridays, 35. The two fully automatic machines operate at full capacity on peak days. The team has adjusted its inventory planning: beans and milk are restocked on Monday afternoons and Wednesday afternoons. Service visits have shifted from a fixed monthly schedule to a cycle based on the actual number of cups brewed. No more empty machines on Tuesdays, and no unnecessary service costs during quiet weeks.
Peak office coffee service demand requires a schedule that adapts to actual occupancy levels. Align your machine capacity with the busiest day, adjust inventory and service to match the rhythm of Tuesdays and Thursdays, and include response time agreements in your service contract. This ensures that coffee is available when your team needs it most.
Frequently Asked Questions
How big is the difference in coffee consumption between peak and off-peak days?
During peak times, 50 to 60% of employees are present. On such a day, coffee consumption can be two to three times higher than on a Friday, when 18% of workstations are occupied. The exact difference depends on the size of your office and your coffee culture.
When is a second coffee machine needed for busy days?
First, determine whether your current machine exceeds 75% of its daily capacity on peak days. If so, it would be worthwhile to invest in a second machine. If peak loads are lower, it is sufficient to better align inventory and service times with Tuesday-Thursday occupancy.
How often should maintenance come by when staffing levels are uneven?
With heavy use, maintenance may be required every six to eight weeks. Schedule service visits after peak periods rather than on a fixed calendar day. Discuss a maintenance schedule with your supplier based on actual usage.
