Waiting for the bus after work, very young and new to work. Whilst waiting 2 cool boys I knew got off another bus and stopped to chat. We all lit up. My bus arrived, a queue of people got on. I didn't join queue because I was smoking (and with cool boys) and assumed the bus driver would recognize me (???).
After the last person got on, I throw fag away and step onto the bus.
The bus driver has assumed the last person has got on and paid (this was, obviously, many years before oyster cards. Or any cards!), and he had pressed the button to close the doors. Which is on a slight time delay
In that time delay, I step onto the bus.
The doors close.
Pinning me, one foot on the bus, one in mid air getting onto the bus. My arms pinned at my sides (this was the worst bit... I couldn't flick my 80s flick-y fringe).
The bus driver couldn't open the door for several seconds (each one feeling like hours) because he was so busy pointing and laughing.
Cool boys almost wet themselves, and have referred to it ever since. It was 30 years ago. Still cringe!
(have been caught having full sex several times since [not a dogger, honestly] but being stuck in the bus door was worse!)
p.s. The driver gave me 2 or 3 free trips afterwards because I'd given him "such a good laugh"
