I think I have always had a natural gift of problem solving and figuring out better ways to do things. For years I read advice from guys saying you have to be a regular and speak to bartenders to get extras. However I managed to use three common things I noticed about certain dancers to let me know they offer extras. I put it to the test today with 100% accuracy every girl I went upstairs with gave a HJ and the first two I told to stop before I finished since I was only testing a theory. The third chick I was ready to leave so she finished me off.
I am not sure if I should let out my secret tactic as it may be used by others to stop extras but I will offer one easy hint... one being the girls that are not really lap dancing and take long pauses without moving with their head looking down are likely doing a HJ. There are two other hints and when combined it's likely she offers extras
