The Night I Saw a Man Watching Me Outside a Bar

I used to work as a bartender or bar that closed at midnight. My coworker and I would often go out for a drink after we had finished closing the bar down. We ended up sitting outside of the bar on the back of my car and talking. It slowly dawned on me that he had seen me sometime around 1am when I arrived. He must have been sitting in his car just watching and waiting for me to leave. So this was about three years ago and it still creeps me out.
