I couldn't decide if this should be a complaint or compliment because it is actually both; I erred on the side caution and went with a compliment because of the way it was ultimately handled.
I had four tires put on my car at COSTCO, they cross threaded one of my lug nuts and destroyed a second one (both on the same wheel); the bad part is they let me drive off without telling me. I was not happy when I saw the missing lug nut.
I called the Tire Center and got little satisfaction, so I went back and spoke to a manager. He was apologetic and offered to pay for the repairs plus a $50 gift card. The repair was $131; I took my receipt back yesterday and got fully reimbursed and got a $50 gift card with no hassle.
COSTCO is still one of my favorite stores, they hire great managers, but I don't think I'll let them touch my tires again.
