The staff canteen is a natural place for an after-meal coffee. Make sure coffee is available outside lunch hours too.
In a staff canteen, coffee works best as a separate point, apart from the food counter, and available outside meal service hours. A self-service device lets staff get coffee without involving canteen staff.
A separate point
Coffee at the food counter lengthens the line. A point near the canteen exit spreads the traffic.
Outside meal hours
Canteens are often open longer than meal service. A self-service device runs independently of the kitchen. The page on vending in canteens (publisher's site) covers such setups.
Tidiness
A bin for cups and stirrers by the coffee point keeps tables tidy.
FAQ
Do canteen staff serve the coffee? It depends on the setup. Self-service takes pressure off staff at peak times.
Can the coffee point run around the clock? Yes, if the canteen or a nearby area is open to shift workers.
