Nice to hear that your interview went well.
Boo on the people working in the shop, but this should be a lesson to us all. Do your research.
This kind of crap happened to me yesterday at the car dealer. They said I need 500 dollars work of general maint. done on my car (without ever driving it or even looking at it just going by the milage). I checked the maint manual. WRONG! I don't need any of the work for another 30,000 miles! lol guess what they won't be doing the work when it is time to get it done!
