Some of the carry out places I frequent have tip jars, and the credit card receipt has a line to write in a tip. I always feel awkward when the guy at the register looks at my receipt and I didn't tip. But I don't see why I should be tipping - I walked my ass over to pick up my own food. Any work they did should be included in the price of my order, no?
landing spot. will be interesting to see how he does.
