A guy who stays regularly at the hotel I work in, all the female staff know to avoid getting caught alone with him.
He has a habit of asking us if we know of any “adult fun” nearby. If you just act like you don’t know what he’s talking about he’ll say he wants to go to brothels and have a good time without his wife. He’ll then progress to offering you various amounts of money for the night and asking you what you like in bed and what you’d be willing to do. He developed such an obsession with one of our staff before she left that security would walk round with her when he stayed because he’d followed her out to her car at one point making suggestive comments.
Got stuck alone with him once as I was behind the counter and he stood blocking the only way out from behind it. He started the usual chat and I told him I wasn’t interested. He then moved on to asking me what time I finished, if I lived nearby, if I walked home alone. My male coworker turned up then but he creeped on me from a distance the rest of the day and watched me leave. I have no doubt he will assault someone one day, hotel won’t ban him because he regularly spends money.
