I don't see why escorting is any different to any other industry.. There is a small amount of those who excel at their vocation; the majority are average and there is a small amount that are worthless (usually bigger amount than those who excel). Also, in other industries, you are likely to get better service if you click with the person providing the service than not; how many times have you gone out of your way to help someone you don't get on with in your business? Also, you have to set your expectations accordingly - if the WG doesn't advertise GFE and it has not been discussed/agreed, why would you be unhappy that a GFE was not on offer? [edit] Or, more accurately, if she was not really making you feel like she mattered to you beyond the transaction?
I don't punt anywhere near regularly enough - about mid last year was the last time I punted.. (I sort of moved to strip clubs for a while, too). However, like in normal work dealings, I find that if I respect people, show interest in them and are sensitive to what makes them tick and what stops them ticking, more often than not they are receptive and adopt a far better disposition than not. And at work, the person with the BO general lack of hygiene isn't going to be the one people want to spend a lot of time with.
So much like RobT22, most of my punts have been quite good... even those that have started off precariously.. There was one in Euston about 15 years ago - it was a lunch time walk from the office needing to scatch an itch - no real due diligence except a tart card in a phone box. Called, went to the house, the madame trollied out a bunch of young skinny girls - never really been interested in that type even when I was young. I went with the one that I though would be least sterile... And I could tell she wasn't terribly impressed to be providing a service to me. But I simply treated we well and took interest in her.. her mood changed and it was a great punt.. she went from being very mechanical to at least giving the impression she was happy to provide the service quite enthusiastically, too. It was too long before I joined UKP to write a review (wouldn't have remembered who it was).
I am satisfied with most of my punts.. There have been a few that just didn't go well.. Some have been where I was probably a turn off to the WG and there has been at least two I can remember where in the end, the WG was just not for me and no coaxing from the WG would get me into action.
