Better off watching the original program which was on ITV
I have read independently that getting people drunk and racking up massive bills happens in strip clubs so cant see why it wouldn't happen in a brothel but its obv going to be limited to certain wealthy areas.
It was very widespread in Soho and may still be so for all I know, clip joints they were known as, I had to fight my way out of one in the 80s with a mate, we went in and a looker took our coats, then we were asked to pay £80 for half a bottle of cheap Champagne when we refused a big ugly fucker started to threaten us. We got our coats and legged it.
I have never experienced the same in any brothel I have been in and that's many hundreds, loads of bad WGs and some dodgy pimps yes, trying to get me drunk no. I have been threatened verbally though and had a few WGs who I thought were going to get violent but I fucked off. In my early punting days I never punted when I wasn't pissed, stoned or both and had little trouble but that is a long time ago now.
