It’s rare that I’d ever have a $100 bill in my wallet, but I just got back from Vegas and fortunately I didn’t spend everything I had!

I stopped at the Exxon Mobil station here in Austin off of 183 and Braker to put some gas in my tank and all I had was a couple of $100 bills. I walked inside and told the cashier that I wanted $40 worth of gas, and then I show her the $100 bill.

She says, “Don’t have change for $100″.

I think, okay, it’s the middle of the afternoon, maybe they just made a bank drop and don’t have change. No problem.

I say, “okay, let me have $60″. I knew that my truck could easily have room for $60 and they must have $40 in the register.

“Nope, don’t have change for $100″, she says.

How does a gas station not have $40 in the register? If it was in a bad part of town, I could understand, or even if it was at night. But early in the afternoon in a better part of town?

I have nothing against the oil companies, but how the hell does Exxon Mobil not have change for $100? I just read the other day that Exxon Mobil posted $10.9B profit and they don’t even have change for $100?

After I walked out of the gas station I realized that she probably meant that she wouldn’t accept a $100 bill. Because there is no way they “didn’t have change” for the $100. But still, that’s no excuse to not accept a $100 bill. If my truck were on empty, it would cost between $85-$90 to fill up at today’s gas prices. But still, they wouldn’t take the $100 bill.

Rex Tillerson, CEO of Exxon Mobil, made more than $16.7 million in salary and bonus in 2007. Hey, Rex, do you think you could break a $100 bill?
