Ok, it's an autozone... but seriously this one was pretty good for the service. As soon as we walked in we were greeted, and there was a guy in the back willing to help us as soon as he saw that bewildered look on my, "I don't know what the heck I'm doing" face.
He walked over and told the me benefits of each product and the ones that were crap, and not to use. He was patient despite the line forming to ask him for help, and he assisted everyone he could quickly.
Wait time at the register was also quick and the lady working was funny and super pleasant even though a customer had just given her a hard time. I would come back for all my "I don't know what this thing a ma bob for my car does..." moments. :)
