Who wants jack daniels?

Yeah. Well, maybe not. Do your wheels need retruing? Its possible, if they're a shady shop, that they might do a half assed job on the wheels because you refused to pay for the cog. On the other hand, if you were told $22, you were told $22. Its unreasonable for them to expect you to pay more. I worked in retail long enough to know that sometimes people screw up, but the store needs to take the hit to keep the customer happy. If they refuse to make you happy, they don't care about you, so why should you care about them?
