I took my car for service. There was not one, but two coupons for the dealership laying right on the passenger seat. AND I told one of the people who helped me. AND there are coupons on their website for service. Surprise, surprise, the coupon for 10% off the repair was NOT given. And the cashier couldn't help. The service guy claimed innocence.
I've walked away with that "dealership" feeling. It's the little things that make a difference whether or not I'll go back.
