I've been on a city bus several times when the driver just pulled over, turned off the engine, said "I'm going to the bathroom", entered the business he'd parked in front of, and came back after a couple of minutes. It didn't cause a problem, so municipalities who don't allow that are abusive. I'm sure that in general drivers try to keep that to a minimum.
