Alone with the Saleswoman in the Closed Fitting Room

When I tried on some pants and asked for them to be hemmed, the lady behind the counter crouched right in front of my crotch to take the measurements. It happens sometimes, but having a woman’s face that close to a man’s crotch… If you get an erection, that’s bad news, right? But what if you actually exposed your erection… What would happen to the saleswoman in the midst of this crazy mess in the tiny fitting room?
