My car had trouble starting, so I took it to Desert Car Care, down the street from my office, to get my battery tested. It felt like a dying battery to me. I arrived at 12:15-ish. The lady said that everyone was at lunch, but she could check and see if someone was available to test my battery. She came back and said "Actually, we can't get you in until Monday." I stared blankly. Then she said something about a full diagnostic and blah blah blah.
I couldn't believe that they would let someone drive off with an iffy car battery in this heat. I drove to AutoZone (thankfully my car BARELY started), and they tested AND replaced my battery within 10 minutes.
They don't seem to care about people much. Especially if it's their lunch break. Guess what? It was my lunch break too. Ten minutes to help out another human would have made you some money now and a customer in the future, and would have been the kind and right thing to do.
