You can just put theirs on the clean table or in a dryer; it's a common thing to do. But I wouldn't turn on the dryer--some stuff could be damaged by that.

This is how people wind up with their wet clothes on the folding table.
Don't want your wet clothes set on the folding table? Set a bleedin' timer FFS.
Ugh, I don't miss apt living AT ALL.

Usually do mine at home , but on the very rare occasion when I had to go to a lanudromat , I've been fortunate that the closest one is well run , very clean , and if there's a concern , I can ask the ladies who take care of the place , about the protocol before I consider removing someone else's laundry . No real problems there .

I don't play with that shit. If it's been sitting in there a while I take it out and leave it on top of the washer. Sometimes I would even get my stuff dry and be gone before they came for their stuff
