How much I tip really does depend on the service... The awful waitress I had at a local place the other night got just under 10%, great service can get 20-30% (partially depends on the total bill as 30% is more likely when at a business trip where we have split checks and the check was only $10 or we went to a place and only got dessert the other ones that sometimes get this much is the servers at places we go all the time and they know just how we like things, to the point that we don't even have to order and our drinks are being brought to us as we sit down)
A few other notes on what I do:
Problems with the food only cost the servers tip if its something they really should have noticed. If DH ordered barbecue sauce and was brought honey mustard yeah the server should have noticed. If a steak was ordered well done and its bloody on the plate its obviously not well cooked and they should know that. However if my medium steak is really well done... yeah I don't expect them to be able to tell that just by looking at it so unless they give me attitude about getting a new steak I won't change their tip.
Buffett places I will tip about the same as I do normally if its the kind of place that still does your drinks and keeps clearing plates. AT the kind of place where I get my own drinks and they just make rounds every so often to get plates I'll do a bit less.
