Why do we bitch when oil companies make really a very small % of profit/unit especially compared to other consumer goods?

I would love to own a company that sells a product as high in demand as oil, its not their fault. One day oil wont be in high demand and what ever the next form of energy is needed I can assure you that people will be complaining of those companies too!

I mean heck, we pay like $2.50 for a glass of sweet tea at a place to eat that cost them what, like 25cents?! Or what about those $4 beers at football games? You cant tell me that that isnt "price gouging!" Why arent we bitching about all that?

Ive never really complained about gas prices, after all its a product I need and I will pay what I have to to get it. If the price is too high to justify the cost I and every one else will find something else. So far it isnt.
