Honolulu, HI
I went in to the shop because my check engine light was on, it had just come on, and this was the first time it had happened to me. Turns out, I had to pay $145 for them to screw in my gas cap which should have costed me $0 if the sales person was nice enough to educate me about the possibility that it was the gas cap since she asked when I filled my gas several times and I confirmed that I had just filled gas last night. Ended up learning a very expensive lesson. Thanks Lex Brodie
