High gas prices are costing local convenience stores in another way, gas drive offs.
Now, cashiers are having to desert their honesty policy when it comes to filling up.
Big signs are posted on many pumps advising people to pay before you pump.
One gas station in smith county was even advised today by the sheriff's department to start the "pre-pay" policy with gas prices still high. Another clerk says it is her responsibility to make sure the gas is paid for.
"I have to pay for it," says Leslie Dunn, a convenience store worker.
"It's hard enough to pay for gas for your own car much less say three times 30, 90 dollars a time. It's just too high so I make everybody pre-pay."
Anyone who is found guilty of stealing gas is looking at a pretty hefty punishment. The crime is punishable by up to six months in jail and a two thousand dollar fine.
