Thanks for all of your advice.
I went down today and the manager was properly staring at me (unfortunately I can often read what people are feeling or thinking due to being an empath) but I wasn't too bothered - also, I had my personal phone in my hand when my work phone started ringing at check in. Not much of an obvious sign, but the female I checked in with was in heels, has fake boobs, heavy makeup, and the fact that she was paying by cash just makes it obvious to me.
I wasn't that busy today so cancelled the hotel at 2PM and stayed here. I will take any bookings that I get here tomorrow and just let them in (I am going down in normal clothes now and just stripping to my lingerie and putting heels on when they get up here). If they kick me out, they kick me out.
Had one prick today who had the apartment name but claimed he couldn't come due to a 'man being on reception' like it isn't me taking the risk. Also, had the 1.5 hour guy cancel on Monday night due to it being a 'dodgy area', think he was chatting shit but I had made him buy me a Paysafe voucher prior to even considering the booking as I thought that he might be a flake so I got that at least.
Thanks veggiegal, it was a bad move of me to naively trust someone and it was completely my fault. Like you said, it is best to go it alone and I actually prefer that.
Onward and upwards hopefully from now on anyway!
