Once had a girl come to develop pictures, and she asked to fill out a job application while she waited.
I drop her roll in and set her up on the computer.
The film develops and I go to print. All of the pictures were of her doing illegal drugs.
After trying not to laugh my ass off at the situation (in front of her, anyway,) I just walked over and told her, "By the way, we drug test."
She quit the job application, paid for her pictures and hauled ass out of the store. LOL!
