My brother's previous place had such a small bathroom he couldn't even fit a washing machine in it, so he used to just bring his dirty laundry with him and wash it at our grandparent's place instead of messing about with the shared room.
Plenty of angry notes have been left and many a neighbour feud have begun in those most haunted of halls when people have gotten their hours mixed up or left their stuff in the machine for too long, after all, so best to just stay clear away from them if possible.
Or so the common stereotype goes.
I've only been to the one here once because I had to wash something that required a more heavy-duty machine than my own (there's another point. Industrial-grade washing machines will never not look scary >.>), and that was more than enough for me.
