He did have a tire pressure gauge in the car so I took it and check his tires for him and the pressure needle pegged to the max reading! Oh CRAP! I yelled at the guy telling him that his tires were extremely over inflated and could potentially explode in his face or even worse, explode on the highway causing a wreck. I proceed to deflate his tire back to the recommend pressures.

I wouldn't have believed that people can be this clueless out there but I have seen it first hand. If I remember correctly the gauge read around a 100PSi or so but I don't exactly remember since this was around 17 years ago. I've never driven with this couple again.
