Where buses go to sleep

Where do buses go to sleep? And – more importantly- who puts them to sleep?

In the evening, when the buses have finished their routes, they are brought to the depot. There Nurcan and Marinko wait together with 5 others. Nurcan is Turkish. Marinko is from Croatia. The others are from Portugal, Albania and Syria. Every night they care for the buses – cleaning, washing and refuelling them. Into the early morning hours. Again and again. Refuel, clean, wash - and wait. Until all the buses have gone to sleep. Every night.
