On the other side of the coin . . .
I knew a guy who was a tech at a Lexus dealership. Back then, they had to try and accomodate you whenever you came in, regardless of whether you were an asshole and missed your appointment. He would tell me about filthy rich inconsiderate people who would abuse their policy. Like this one bitch who came in at 5pm on a Friday night for an inspection on an LS400, and she said she needed them to deliver the car back to her house by 7pm the same night
