Are they good for anything?
There's a whole bunch of them in Broker and Dukes. However, I don't seem to be able to use them, apart from taking cash from register. Whenever I walk up to somebody inside, they say "f*ck off!" And when I walk up to any of the washing machines there's no action prompt.
So is it possible to clean your clothes in laundromats or not? They sure could be useful. Like for instance I returned after battle against cops and noose to deliver lawyer's files to Francis - in cutscene Niko's suit was all covered in blood and guts.
