I'm so sorry to hear about what happened to you
I was scammed by this guy when I was fairly new and he did the same thing to my friend. Same thing, said he was Arabic but spoke with an English accent, very skinny, requested baby oil, met him in a Travelodge, offered me way more my usual rate (I think it was 3K for a few hours?) and brought a bottle of Absolute vodka. Unfortunately I don't have his username or number any more because it happened so long ago, but watch out for those signs. Really taught me that if something sounds too good to be true, it probably is, and to always ask for a booking request over AW. When I got to the hotel, he threw the keycard out the window to me because he said didn't want to be seen with me by reception. At the start of booking, he laid out all the money on the bed, counting it as he did. He said it was all for me and put it into an envelope. I went to take it from him, but he said he'd been scammed by a girl who ran off with his money, and that he wanted to leave it on the side where we could both see it, so I said okay. After we had sex, he asked me if I wanted to take a shower. I replied that I didn't want to or need to. He kept on insisting that he wanted me to take one because he was funny about cleanliness so I did. While I was in the shower, he switched the envelope to one that was filled out with cut up newspaper. I remember him encouraging me to drink but I hardly touched it, as I don't like vodka. After we'd had sex a couple of times, he called to get a takeaway (I think it was pizza?). He went out to collect it from the reception and then called me while he was outside to let me know that he'd had a change of plan and had to rush home. Then when I got home and opened the envelope, I realised that I'd been scammed. If anyone has his details and would be up for going to police to to report him for fraud, I would be totally up for it. There's a sex worker liaison police offer at my local sex worker group, who can keep your identity in the report anonymous.
