Arrived at the dealership for the recall fix. I asked the service writer chic if she was in a good mood and would "comp" me a reverse camera flash. She told me she wasn't in a good mood and that she had to charge me $100. I told her I'd take a pass.
About an hour later, she walked into the waiting room and told me she had experienced a change of heart and was going to throw it in. Told me not to tell anybody, so don't ask me where I had it done. When I go back for my last free oil change, I'll take her a gift card to a nice local restaurant.
