They also do this as sort of practice runs.
In hotels, the week before opening, they get guests to stay free of cost and ask them to order room service to check if the food is delivered on time, if it's on appropriate temperature etc.
A housekeeping staff has to clean up the room in 7 mins flat including toilets.
I was part of this experience once.
We were given timers and give ratings to the service.
wow what fun… but it is necessary
