Have you ever caught the opposite sex in the wrong chancing/rest room?

I never haven't caught the opposite sex in the girl's chancing/restroom. But I have accidentally walked in to the men twice. 1st time I was 9 or 10 and didn't realize I was in the wrong one until I was done thankfully no one said anything. 2nd time I was in my late teens/ early 20's I was on the swim team and you have to go through the changing room to get to the pool and a guy told me I was in the men as embarrassing as it was since I already had my swimsuit on and was already in there I just walk thou the rest of the way.
