I don't think that garage forecourts themselves are heavily profitable?
There we go then. We are all agreed. Because thats what everyones point was in the first place - that garage forecourts dont make loads of money, and many of them are not even owned by oil majors anyway, even some of the ones branded as such!
Hugs all round.
The fact that pulling black stuff out the ground and flogging it on the NYMEX futures exchange is hugely profitable isn't really relevant. As an aside, the actual cost of raw crude in a litre of fuel is very small in percentage terms.
One thing, though, is very big in percentage terms. I think it's called tax, and tax on a tax.
