I can top that :).. since i see all of my clients in person, except for a few clients that live in different states, I hardly ever even mail tax returns.  Client comes out to my office.. I greet them. cut the chit chat, prepare the returns, print, they sign, pay me and I thank them and say have a nice year.. (I may cut the have a nice year part as it really means nothing.. me saying have a nice year does not guarantee they will have a nice year and it does take time to say it.
