Getting locked in a public restroom

I was at mcdonalds once with my ex and I knew I always had a hard time with their locks but I had to go to the bathroom anyway so while he waited for our order I went there and then I couldnt get the door open again. In the past when that happened I took off my shoe and slammed it repeatedly into the lock but it didnt work this time. All of a sudden I hear outside the door "yeah I think they cant get out" and then the door opens from the outside. Someone had noticed me trying to get out and went and got someone who worked there to open from the outside. None of us said anything, I just stared at them and then hurried out of there and up to my boyfriend like "okay lets go" and then we left with our food. One year later I got a job there. I hope they didnt recognize me xD
As a kid I used to be unable to know how to use the lock properly so at school I never locked the bathroom door and someones another kid would open it while I was peeing and be like "oh..." and back away without even closing the door properly so I had to get up with my pants by my knees and close it...
