I had a guy bring his car in and I installed a Yellow top Battery, Alt, amps, subs & a deck. It was a acura integra. I noticed when I was under the hood that it had a new motor in it. It was an H22 out of a prelude. Anyway, dude calls me up an hour after he left my shop and said I broke his A.C. I told him to bring it back up to the shop so I could look at it. Well it turns out that he just bought the car and didn't know that the A.C. had been removed to make room for the new motor! He just thought it was broken and was gonna have me do work under the hood and blame it on me. When I explained to him that he didn't even have A.C. he got pissed and hauled ass! I'll never forget that shit.
