Curious

I have another thread along the same lines, but my thought process was that if I don't haggle with and I don't tip my Lawyer or my Doctor (people you pay for their expertise and time) I assume the running charge rate is already priced to their comfort.

Not generous really very self serving, I think it fosters an extremely professional experience. I forgot to add that I am a pretty demanding person in terms of being on time , dressed for the occasion, and maintaining the appropriate professional distance. I think the saying goes "we aren't paying them to stay , we are paying them to go away"
