I figured it out. I had the problem for the past 15 months and it was driving me crazy. And the workaround solution is very simple.
If kitchen and canteen/staff canteen are not separate rooms, e. g. surrounded by walls and instead using a shared room, e. g. kitchen on the left and canteen/staff canteen on the right without any walls or doors between, food trays may end up on the floor. If the floor does not belong to the kitchen, they will remain there forever and pile up, until staff complain, that they are getting no more food.
The workaround: Assign the floor, with the piled up food trays to the kitchen and cooks will jump from everywhere and remove it / clean it.
Still, I consider this behavior as a bug. Cooks should also pick up food trays from non-kitchen areas and I would appreciate it, if this bug could be fixed.

This bug exists for more than a year. Please kindly fix it.
