We've all been there in one way or another. The worst one for me was a few years ago, client had booked and hour, he arrived and gave me the cash all folded up, I didn't count it and put it in my drawer. We got down to business, finished all the sex stuff arkund midway and then lay chatting for a further 20 min or so before he got showered and left, bang on 1 hour. After he left I counted the cash to find my half house rate, which was £60 less than my hour. I text him immediately and he did reply saying he wated to reduce to 30 mins and just thought I wasnt being a clockwatcher when I allowed him to stay a further 30 mins. He made no mention prior or during of reducing the appointment so the prick knew fine well what he was doing and because I was new, he got away with it. That one sits deep with me.
