My own experiences are that I have always found a great escort when I have used it, especially in London as they are nearly always outcalls and hence the bidders are serious. Yes I have had the silly bid amounts and those that are miles away and maybe won’t travel, but they have made up a very small fraction of my bidders.
The only thing I have found distasteful is when I send the ‘thanks, but no thanks’ email a few escorts get a bit sarky. Most say thanks and one or two of them got booking from me later.
