shared laundry facility question

At what point is it acceptable to take someone else’s clothes out of the washer/dryer in a shared laundry facility?

I’ve seen washers with clothes still in them up to an hour after being done which to me seems a little ridiculous. We all have an app, it notifies us when it’s done and if not the app then you can set an alarm or timer on your phone right??

I obviously expect some wait but how long of a wait is too long? 10, 20, 30 minutes? And is it socially understandable to take clothes out of it’s been too long.
