AITA for pretending I didn’t recognize my coworker outside of work? So this happened yesterday and I can’t stop thinking about it. I (22M) was at a supermarket after work, just trying to grab some food and go home. I was tired, still in my uniform, headphones in — not really in the mood to talk to anyone. While I’m in line, I notice my coworker a few people behind me. We’re not close, but we work the same shifts sometimes and chat a bit.
