Had one turn up to my hotel room tonight. The first thing he said on arrival was that he hadn't read my profile and wanted me to go through everything I did. I just then got a really horrible gut feeling and directed him out of the room then he started to ask again what I did. I said I was sorry but I couldn't go through with it. He got really angry and said he was going to report me to reception and take photos of my door. I walked away and he started shouting for me to give him back the 15 pound diesel money. Of course I didn't. Maybe I should have. But I was just shaking like a leaf. I just went in my room and shut the door. Two hours and one client has passed since then but nobody from reception has been up to throw me out-yet! Don't know if worth trying to sleep in case they knock an hour later with the police lol. I feel a bit guilty too because maybe the guy had driven a long way and maybe I should have just told him what I did and didn't but in this case I just panicked. :-(

His behaviour is not "partly" your fault. His bad behaviour is in no way your fault. It's HIS fault!

Had he read your profile, or even had a quick glimpse of it, he could read exactly the service you offer.
He did read your profile as he made an appointment. He's simply a chancer on the make!!

As for his claim to wanting diesel expenses - he probably was local and within walking distance of your hotel.
He probably plays the "?15 for diesel" party trick regularly. I've experienced the exact same in North London recently.
The potential client claimed he'd travelled "all the way from Watford" for a specific service. A service I quite clearly do not provide. Just a coincidence, but he looked Turkish too!! Mid - late 40's, well built!!
