I had one, texted her for a booking, but asked if she could do 45 minutes insted of 30 or an hour. She sort of hummed and hawed a bit and said it would only be a one off so I said OK, if it was a problem I'd look somewhere else, I was perfectly polite about it but next thing I get a stream of abusive texts calling me a cunt, a twat, a miserable old bastard and anything else she could think of. We hadn't even agree a booking and had only swapped about two or three texts. Real weird. Needless to say, I've never tried to book her since.
