It happened to me a few times. It's worse when the train is still at the station with the doors closed and you're pushing the button for them to open but they don't and it sets off.
If that happened I could never make eye contact with any of the folk staring at me out of the train windows. Gutted.
aye I've had that before like, don't want to look at anyone because I just know some will laugh at me and I'll get pissed off/ even more embarrassed. Since I've been on the receiving end I've got no idea why I like seeing it happen to other people, must just be a knob
