What's wrong with this picture - redux

I won't bore you with a rant on how expensive gas is.

But if I'm going to pay nearly $4/gallon, I deserve better signage.

I know how to pre-pay,

and I know how to pay in advance.

But how exactly do you prepay in advance?

Does that mean I have to pre-prepay? Prepay even before I've thought about paying?

Ugh.  Someone buy me an electric car.
