The small apartment building I live in is set up this way. I don't really mind, but I wish they would find a way to accept cards (credit and/or reloadable) rather than only coins because as it stands right now, I have to go to the bank and get $50 worth of "laundry tokens" (quarters) every few months, since I don't spend enough cash day-to-day to naturally collect enough change for the laundry.

That's very interesting. In my MCOL of city I've been looking at buying some apartment buildings and many of them advertise the W/D in the building as a source of revenue.
