Does this happen in the men's restroom? Because sometimes as I'm finishing up in the restroom, I hear a lady come in and settle down in a stall.... and then do nothing. They need to have absolute solitude before they can dare to expose their bodily functions. So they sit there and wait for 2 minutes while I leisurely wash my hands. The best is after lunch at my job because not only do I wash my hands, but I also brush my teeth, while that dumb lady sits in the stall anxious as hell because she's afraid to piss or shit where others can hear.
This is not an isolated incident. I have been known to fiddle around for several minutes in the bathroom just to mess with these kinds of ladies.
