I feel really weird for asking, but what do extra services from a pre-op LB consist of? Obviously a RnT+HE, CBJ are possible, but do you get into backdoor territory?
If the LB starts to get hard, do you as the customer feel that you have some sort of obligation to reciprocate the pleasure? Or do you leave the LB hanging with blue balls once you've popped your load?

Not trying to be a smart ass, I'm genuinely curious.
