Pizza/sub delivery is usually $3-$4.
Although one evening I ordered a pizza for just DS and myself (total price as about $12). I gave the delivery person a 20 and said "Just give me 5 back." Well, he told me that he didn't have *any* change on him. That made me a bit angry (he seemed to be *expecting* me to give him an $8 tip). So I took my 20 back and said, "What are you going to do about this?" It ended up that I hade a ten which I gave him. So not only did he not get a tip, but I didn't even pay enough for my pizza. Really burned me up and I called the pizza place to complain. I ordinarily tip well, but I can't stand it when a large tip is *expected.* I actually felt kinda guilty after the whole thing was over, but DH (who I called to tell about the whole thing) tried to make me realize that it was the delivery person's responsibilty to have change.
