One older guy came in asking about photography and whether we had a "specific image" of a rock he saw 300 miles away. I responded in that, no we didn't and that he should probably go take the photo himself. He goes, "I can't. I'm writing a book and I need this image for its cover."
He looked at me, wanting, wishing me to ask what his book was about.
I got a weird vibe and instantly regretted asking "What's your book about?"
He says, "Possession."
I'm like "Okay, cool man, I like a good scare."
He's like "No, no, no. Possession is where an older man controls and orders a young woman like you to be his slave. Would it be a topic you'd consider learning?"
I can't remember how I ended the conversation, but for about 6 or 7 months he'd keep trying to talk to me and ask weird questions. He stopped when he realised I wasn't as young as I looked, or easily influenced.
He is so creepy.
