So you open yourself up a nice little hoagie shop in town. Everybody runs to it. It's great. But why at the end of the sale are you asking for a tip.? All you did was make me a hoagie. Asking for a tip. Is increasing the amount of money you're asking for the hoagie. Now, if you open the door for me when I came in and left I'd give you a tip but all you did was make me a hoagie. What am I missing here?
