A sushi place in Watertown, MA

A sushi place in Watertown, MA has a set-up in the ladies' where you walk in and there's a commode. Just ahead there's also a stall door, behind which is a second commode. Everyone must experience the same rapid sequence of thoughts as they're welcomed by this set-up: you stand there for a few seconds considering going into the stall...but then what if someone comes in and uses the commode outside the stall? Then you have a half-naked squatting stranger between you and the exit door as you're trapped inside the stall. Do you wait until they finish and leave? Do you come out when you're done? What kind of small talk would occur as you're washing your hands in the sink ten inches from her head? Then you consider using the first commode...but then YOU'RE the squatting stranger that another woman has to walk past to get to that stall. Thankfully there is a lock on the door, which is surely what everyone decides after a moment.
