I was in the Wal-Mart this evening on Rittenhouse/Ocotillo where a woman had had her tires put on there (brand new) and the ding dongs didn't tighten her lug nuts enough and 2 of her tires came OFF as she was driving down the road. Luckily she said she was only going 15 MPH and so she had minimal damage but she had kids and she was more concerned that these ding bats are working on cars and being that careless and that either her children or someone else's children could possibly be killed because of their negligence. Anyway, one more reason not to head to Wal-Mart for ANY auto service. I've had a couple of family members say they wouldn't go for oil changes and such but hey tires how can you mess up tires, yeah well that's how. So just be very careful who you choose to work on your car no matter how small the work seems.
