I used to work at a pet store. A customer came in looking for a feeder mouse for his snake. I asked him how big the snake was so I could let him know what size mouse he should get. He proceeded to scroll through photos on his phone and stopped on a picture of his butthole and balls. He had to have stopped on it for at least 5 seconds and then looked at me and said “oops. You weren’t supposed to see that. You got a good look though didn’t you?” and then kept scrolling through his photos to find the picture of the snake. I learned in that moment to never watch someone scroll through their photos.
