Tipping is expected if you go to a full service place or get delivery. If you do not care to tip, go pick it up, or go to a fast food place. There's nothing wrong with either option, as my wife or I often go pick up our pizza or Chinese, as it's well worth the $4-5 savings in delivery fee plus tip for us to give up 15 minutes and a mile or three. I delivered for 5 years back from '90-'95, and while it is strange why some get tips and some don't, it's tough to make an argument for not tipping without coming off as frugal and/or cheap. Back then, I averaged about 80 cents to a dollar per delivery, and I would expect it's double that now, maybe more. But, if you are ordering $15-20 of food, $2-3 to bring it to your door, often as hot as it was right out of the oven, is about as inexpensive as any service out there.
