There was disbelief among some rental car customers at Reagan National Airport when they learned the price for not prepaying their gas tanks.
Hertz charges a whopping $9.29 per gallon. Avis charges almost $8 a gallon while Budget charges $7.50.
"They sock it to ya! They really sock it to ya," said Hal Miner, a Utah resident.
At those prices, if you returned a Ford Club wagon to Hertz with an empty tank, you'd owe more than $325.
While not everyone had a problem with it, Many said they'd make sure they'd fill the tanks.
"I thought it was a little excessive! And I think I'll fill it myself at those prices!" said William Tangney from South Carolina.
