I've seen many restroom posts so I decided to share one that didn't go so well for the CDer.
We were at a packed nightclub and I was standing in a long line in the ladies room when in waltzes a CDer, goes to the front of the line (mistake #1), grabs the next available stall, and his feet are facing the toilet as he does his business (mistake#2). When the CDer came out, he did not wash his hands (mistake #3) but proceeded to whip out his phone - like he was going take a selfie (mistake #4). In front of me were five ladies that were together (GG's often go to the restroom as a group). One of them became furious (maybe fueled by alcohol), and confronted the CDer demanding to know if he was a man. He proceeded to argue with the "madder than a wet cat" GG, and told her that he, the CDer, was a woman (mistake #5). I won't repeat what she said but it wasn't pretty. His voice was a dead giveaway. At that point, it was more than obvious that he was a man. He escaped unharmed, however that was not the end of it. The women proceeded to tell anyone that would listen about the "man in the women's" restroom and pointed him out. The CDer kind of stood against the wall by himself - again with his phone. I don't know if he knew that she was outing him to everyone in sight.
So, just a few suggestions. Avoid mistakes #1 through #5. Leave the phone in your purse. Don't argue if confronted. Leave!!!
One more thing unrelated to this incident. If you go into a restroom where a mom is dealing with small children, leave - find another place to go. No one wants to accused of being a predator.
On a personal note, I go out with my SO and his CD friends who all use the ladies room. It doesn't bother me a bit. There are many GG's who just don't care who is in the restroom - but just beware, not all experiences may be good ones.
