I'm a lousy tipper. I can never figure out when to tip, and when not to. I totally should tip my mechanic, he's awesome! My car broke down twice last month, which was a complete nightmare, but they are always really nice about fixing it, and have spent hours looking at my car to find a problem, and then not charging me for it. Problem is, most of the time I have to take my car in, I'm really broke, and can barely afford their fees, as low as they are. They will be getting gift baskets from us at christmas time, though!
