Have you ever used a public restroom of the gender you don't identify with?

51. Of course. Most men's rooms have stalls.

Just walk in like you own the place, go into a stall, do your business, then walk out. Don't stop to chit-chat or look at anyone else. I've even seen a couple men make the bathroom door mistake when they were in a hurry - they just ran into a stall to relieve themselves, muttering "oops, my bad" as they do so, then ran back out after they were done. The only women who would have noticed were ones that were by the sink when they ran in (as I was both times), or at the door going in or out.

Common bathroom etiquette actually allows for mixed genders at a public restroom. Even though some people might make small pleasantries when walking into any public restroom facilities, no normal person ever makes direct eye contact; heck it's considered rude to even look at someone unless they're doing something odd. How many people actually want to remember the strangers they saw in a restroom?
Maybe if they noticed a cute pair of shoes, an article of clothing, or there is an "OMG, how did you get that great hair?" situation - but remember the actual person when you are more concerned about no one noticing that you're eliminating waste or trying to make yourself more presentable?
It's one thing if a group of you go into the restroom for a primping and catch-up strategy session. It's another when you run into the restroom because you really got to go...

Other than in North Carolina, the sign on the bathroom is more of a guidance than a law. As it is, in most places, the law only becomes concerned with restroom privacy or gender when there's harassment or a conflict.
