The Old Oil Barrel

I believe it's apparent to everyone that during the holidays and other times when traffic is anticipated to quite heavy, the price of gasoline shoots up. Probably because the gasoline companies know the consumers will use more gas during these times and, basically, they have not other alternative.
If I raised the prices in my restaurants, Bandido's, during especially busy times,like on weekends, I'm sure my customers would have a fit and go elsewhere. Considering this, would it be presumptuous to say, "The gasoline companies literally have us bent over the old oil barrel and show no remorse in sticking it to us...Dicks!"
