Oil Change

I found a coupon for an oil change at the 76 on princeton. I go in yesterday at 1pm and there were no cars in the shop. I figured it wouldn't take long. I tell the guy I need an oil chg and he says to come back tomorrow, he only has one guy working today. I say I can't. He tells me to pick my car up at 10pm (on a saturday). I tell him 9 hrs to do an oil change? Are you insane? Tells me to come back at 5pm. 4 hrs for an oil change? I ended up going to Jiffy Lube and paid a lil bit more and waited 15 minutes lol. You'd think people would want customers to come in, esp in a recession. :)
