I've had a chat with a much discussed CZ lady back in the day and she mentioned on a tour she'd hope to take home £1500 from a 10 day trip after flights and costs. She was 'sweet' but only charged £70 an hour.
I'd imagine it's also 'like buses', they could have nobody for most the day and then get two at once.
With regards to the paper above, has she really been found guilty of running a brothel? Surely they would get her on tax dodging?
