Heck, I went into the wrong restroom at work, and I was 100% sober. Luckily it was empty at the time. A texting and walking incident. Likely all on the security cam.
Done that quite a few times. Not even because I was that intoxicated, but because bar restrooms are often in darfk hallways and if there isn't a urinal you can't tell.
I'll be honest too. In bars I frequent and am well known in? I just use whichever is available if it isn't very crowded.
Yes, I wasn't drunk. The sign on the door said "MEN." Then underneath there was a little arrow pointing to the left and it said in small print, "next door."
