Be thankful she was not dealing with a Firestone. About 5 years ago I took our '99 Silverado in for an alignment (it was under a lifetime alignment agreement with them) and they also performed a courtesy inspection. OK, fine. Anyway, the service advisor let me know that one of the sidemarker bulbs was burned out, and for the small price of sixty-some dollars, they would be more than happy to replace it for me. If I recall correctly, the bulb cost was $6.00, labor was $55.00, and the rest was sales tax and shop fee for consumables.
