That's one of the reasons I love the local Villige Inn here. If I order a avacado swiss burger with no bun or fries instead of charging me for the entire dinner, the waitress will ring up a beef patty with 2 added cheeses (one for the cheese and one to cover avacado) it comes out much cheaper. I've also had waitresses adjust the bill on breakfast items and give me senior prices on meals since I don't have the extra sides.
