Sorry to disagree, but Dinky Dunknuts doesn't count as "waiter" service to me. I mean... I don't tip the guy at the deli for handing me a coffee either. Grabbing a muffin off the shelf? You must make good coin to toss it around like that! :-D
What makes me laugh is the guy with the tip cup in restrooms! What, he should get a buck to make sure the light is on if I gotta pee? :bootysha:
