"Free" tire repair means they'll tell you they can't repair it. When they see you drive up in an AwD Audi, they know if you have to replace 1 tire, you have to get 4. Went to a different shop, $16 to repair the screw puncture. Quite sad seeing that I've spent over $2000 on tires at DT and they just lost a client for life. You just don't flat out lie to a person.
