Thank you for the book recommendation. The entire time the guy was talking to me I was creeped out by him. Mostly because we wouldn't take my verbal (short answers, no questions back, clearly not interested in engaging in the conversation) and non verbal (turning my body physically away from him, not looking at him when I spoke, scooting a little away from him, no smiles, etc) social cues like most people would have.
When I saw that he followed me out and then started his car as I started mine my heart just started beating 1000 times a second. It was an instant fear response. If I hadn't been parked directly next to the door I wouldn't have run back in, I would have done as others said and driven to the police or fire station (the fire station is closer). His behavior just screamed stalker to me, and I got scared. The security guy at the bar (a Marine by day) took me completely seriously, wrote down his name, description and plate and he wont be allowed in again. I also took note of him and his car in case we bump into each other again.
You did just what you should have. He was showing all the signs that de Becker talked about, and you listened to your fear. de Becker says that true fear is your friend, because it tells you when something is wrong. Not worrywart "awfulizing," but real, intuitive fear. And kudos to the security guy for taking you seriously!
I am really, really glad you are ok.
