Well... in my first job I worked in a rundown movie theater so I have a ton of awkward moments.

Similar to Pike's story, we had a lady who would walk up and down the strip our theater was at and come in asking if she could use the phone. She was pretty quiet and demure but as soon as we let her use the phone she would call up her ex-husband and cuss him out and ask him how he liked to smurf his new whore of a girlfriend, along with more wonderful pleasantries. She came by at least once a week to do this...

I also had a time I went into a theater to do a temp check and found that a homeless lady had taken over the handicap space and had unfolded a huge blanket and had bottles placed everywhere like she was trying to set-up a ghetto seance. There was a moment of silence as we stared at each other, and then I slowly shut the door and told managment I wasn't going to do temp checks in theater 5 anymore...
