When I was a poor student, I pumped gas at the West Van shell station. You can imagine the kind of people that came in there.
One douche bag came in maybe twice a week in his STi (this is in 99/2000) and had us check the tire pressure every god damn time. One time I got fed up and told him they were fine, 32 in three tires and 31 in the fourth. He then told me about how in Formula 1 a single psi could make the difference between winning and losing.
I told him he wasn't driving a formula 1 car. lol.. I think I quit a week later.
Personally, I'd put 2 more PSI in because I am just the same douche bag as that guy.

I just know it, and I wouldn't make some poor kid making minimum wage do it.
edit: fucking hell, it couldn't have even been an STi at that time. It must have been only a 2.5RS.. hahaha.
