this actually happened to my aunt but i am posting it for her. she was outside having a cigarette and a man asked for a light. she let him borrow her lighter and the next day he came back asking for cigarettes. when she didn’t give him any he started lurking around and creeping up on people when they were outside for a break, and when they said they were going to call the cops on trespassers he started taunting them from just off the parking lot.
