Then I suppose buying the gasoline wouldn't be optional should not going to work not be an option.Are you sure? Do you know the specifics of his employment? Myself, I am a sub-contractor. I need to drive a truck to work. There's no taking a bicycle. No bus. No walking. Car-pooling? Not really an option.
Point is, I suppose, is that if you need (or really really want) something you pay what it costs - high or not - or you simply don't get it.
One could try to go where it's cheaper but you risk going somewhere with no supply as a result.
I was merely making a rough analogy to make the point, didn't anticipate having to clarify tiny details. I think you know what I was trying to say in my original post. If not, this post should clear it up.
