When I used to work I'd have nightmares. I worked at a grocery store and I was 22, and this older guy (about 50ish) was nice, not ever overly friendly or anything, would do his normal twice a week shopping for a few things and I'd always be there cause it was at night when I'd work. One of my buddies who worked the nightcrew would sit in his car and smoke before work. He noticed there would be a car up in the hotel parking lot which is connected to our stores parking lot and it would always leave right after I did, and I was the last daytime employee to leave the building.
It happened to be the old guy who was a reg. customer. I don't drive I get rides,so my bf would always make sure to be there early after that just cause it's creepy. After 3 nights of him waiting early for me, the old guy got out of his car and banged on his window, my bf said he was super scary looking so he sped off, and called the store to tell me not to go out and have the security guard go out there, and the police.
I guess when the police got there, he threw a fit and punched a cop. So they arrested him.
Apparently he's crazy, He ended up knowing where I lived at, where my bf lived, that I walked in the mornings, and who with. He also had the same info about a coworker of mine, and she had absolutely no idea. CREEPY! I couldn't sleep for weeks. It was terrible.
