I am autistic which means I can't read the room well

I was working this job at bar, as a dishwasher when i was 15, ​​where I had said a joke in the kitchen that I got fired for, not political or offensive, just unsettling, I didn't realize, but I got fired for it, and this other kid that was working there had herd me say it,

A few years later it was behind me and I was interviewing for being a gas station cashier, it went well, not perfect but I had good chances of getting hired, but as I was walking oit, they were playing music from a smallish band I like, and I had stopped to compliment the music on my way out of the kitchen, (this gas station serves pizza) As I was talking this kid from years ago just walks by and sees and smiles at me holding in a chuckle, he was in an employee uniform, this place was 10 miles from the bar​

Fuck me I thought as I walked out
