TIFU by not thinking who would be developing pictures

So a while back I made the questionable decision to bring a disposable camera on a night out with a girl I was seeing. At some point we thought it’d be funny to take a few… let’s just call them spicy pictures.
Fast forward a few days, I drop the camera off to get developed and don’t think much of it.
When I go to pick up the photos, the person behind the counter hands me the envelope, looks at me for a second, and goes, “Hey… don’t you sit in my history class?”
Yeah. It was one of my classmates.
Turns out they worked there part-time and did a lot of the photo developing. So there I am, holding this envelope, realizing there’s a very real chance they saw every single picture in there.
We made eye contact for a solid two seconds too long, and I just said “Thanks” and left like my life depended on it. Next class was… awkward.
TL;DR: Took “spicy” pics on a disposable camera, got them developed, and found out my classmate was the one who processed them.
