enclosed stall? I'm not referring to the quick, "Listen, I can't talk right now, I'm in the restroom! I'll call you back after once I've left here and I've washed my hands." It's more like the guy who goes over the details of an entire multi-million dollar business deal, or the fellow who's getting golf tips from the coach on improving his swing, or the traveler explaining each leg of the trip from Helena to Stockholm and what happened hours by hour.
Eww.
