My charger went bad the night before two projects were due. I brought the charger in without the comp and was told for the apple care warranty to be used, they needed to physically see the comp. The guy was really nice about it and gave me the heads up that if I could get the comp and be back in the store within 15 minutes he would still honor my appointment time or that he could set another appointment for an hour later. I thought it was really great that he showed respect for my time. When I got back they took care of me right away and 20 minutes later I was on my way with a new charger.
