As the others have said, the chat is useful and should be strategic enough to determine whether you're in for a good time or not.
this is true - it's also true that you should see the introductory chat, however onerous it feels, as an investment in a better punt. Women, who I'm reliably informed are wired differently to us, need a bit of warming up - bit of banter, bit of a sense that, the more they can engage with you on an emotional level, the more they will want to have sex with you.
I mainly receive outcall girls, and for introductory punts with new girls, I insist on the warm up chat in my living room over a new world white, as it leads to a much more sexually charged punt. Even when I know it's eating into the time, I still prefer to do it.
