WTF is the point of this thread?
Overstaying any business isn’t a good thing. Time = money be it a SP, electrician, builder or any other self employed job.
I think the point is the SP keeps the punter talking after the agreed upon session is over time wise, and then asks for more money as he overstayed, despite the fact it was the SP talking that was the reason for him 'overstaying'.
Happened to me a few years ago and I had given an envelope with the agreed sum in which she hadn't counted, (as I had seen her a couple of times before), and after I left she started sending me awful texts and threatening to leave bad feedback on AW! She wanted double!
I hadn't instigated the conversation, she was the one being chatty, and then demanded more money. I didn't pay any extra, but did agree a fixed rate with her for future meetings, and told her it was up to her to tell me when my time was up.
Sadly covid intervened and she left AW.
