I went to automotive department to check on a tire leaking air. The guy removed a tire, over inflated it to 50 psi and placed it in a barrel of water to find the leak but found none. He called me over to show no leak. I took a look and noticed he removed the wrong tire! I told him it's the other tire. 45 minutes later( he spent 30 minutes just standing there talking to another mechanic without a care in the world) I got my car. About a week later I checked the pressure on my tires and discovered the first tire the guy checked did not deflate the tire from 50psi to 34psi. Geez! I'll never go back.
