I saw one guy come in wearing pants that had no button, a torn shirt, one shoe and he smelled like a load of fermented panther ****. He was babbling about aliens trying to get him and yet were in the store. As he ran from the "otherworldly invaders," he stopped to pet a bag of potato chips as if they were his dog. We called the cops on him because he went back to his alien visitors. Turns out he was on Meth or something.
I have posted this story before but it is well worth repost. In the summer of 1999/2000 I was working 1230-9 shift. Late into the shift a customer walked up to me and asked me if I still had any of the old strawberries that not for sale and going to be thrown away. I told him sorry that I didn't have any that I could just give away. His response was " darn, the wife's got poison ivy real bad and we were told to smear berries all over her body to help stop the itching." I kid this not. If this would not have happen to me I would have not believed it.
Several years ago one summer there was this one guy who came in several nights a week with no shirt and no shoes. After the weather turned cool, he came in fully dressed and I didn't recognize him at first.
