Overbuilding of fancy semi-privates and the Recession has pretty well squelched such things in our area.
You still have the bag drop and clubs and shoe cleaning at high-end private clubs, but the privates normally have a no-tipping policy..
At the semi-privates, they cut back the amenities like that, just as they have cut back food service to a snack bar. You can get the course caterers to fix a nice meal for an event, but day-to-day is sandwiches and bratwurst off the grill.
Bag drops are mainly used at scrambles, and normally the people handling the bags are volunteers who will also be playing in the tournament.
So in our area, not much of a chance to tip.
