I once saw the greatest business idea. It was called "suds-n-buds". There was a laudromat next to a bar. You bring your laundry in, pop a few quarters in the machine, and while you wait you want something to do. The guy at the front desk hands you a ticket with a number, and you head next door to have a beer. When your wash cycle is done the guy at the counter calls your ticket number. You go back, change your laundry over, and get another ticket.

The owner was making a mint until he died, and his daughter didn't want to own a bar, so it all got sold off.
