If a tip is based on the continual assement of variables and being busy, I suggest it become usual and customary to tip MD's and RN's and not the postman.
Regarding MD/RN's. My wife has a significant, chronic disability and spends more time in the doctors office than you could believe. She is highly dependent on carefully cultivated relationships with her caregivers. One of they ways she helped establish the relationship was doing small things like bringing cookies, saying thank-you and remembering names. Tipping would not be socially acceptable, but this is. Not just the docs, but even the office assistants.
As a result, when she get sick and needs help, the response is fast and she gets to bypass most of the gatekeepers most patients have to contend with. I consider this the same as some of the boat crew I deal with. They know I dive solo and don't hassle me. If I have a late breaking business trip and call, they make room for me. I don't bake cookies for them (that would be weird) but I am no stranger to the tip jar. Sometimes being nice pays off.
