I had a similar experience the other day. We had a 645ci come in, nice guy jokes around, wannabe Mobster type guy. Talking to us the whole time, in the shop, watching us swap his tires over to some [censored] Chinese rims he bought. (275/35/19 runflats btw) No one was a problem with his aux fan, which we ended up diagnosing as a faulty HVAC unit. Programming and installation is around 1800. He freaks, complains about what a POS it is and declines the repair. Picks it up, then comes back the next morning yelling at us that we didnt look the car over like we said we did, we did this wrong, that wrong. 9 am on a Saturday. I said John whats the matter?" "Oh let me show you" Goes to the back of the car and pops the trunk. "Look I gotta lift this thing open now! It used to pop open all the time on its own but now it only goes up halfway and I gotta lift it! What did you do to my car!" Yelling as he lifts his trunk open. I reply, "John, you brought your car in for a repair that quotes 1800, I honestly didnt think youd want 125 dollar trunk struts. If you want we can order them, and Ill install later today wehn theyre delivered" "Oh you'd love that, just rip me off more!" So he hops in his car, and tries to burnout in our lot pulling back onto the main street in front of the shop. But forgets to turn traction control off, which freaks out and cuts the power right in the middle of the street. Stopping traffic with one finger raised, I think we saw John for the last time.
Wow, I feel alot better.
