The price of Oil being as low as what it is:
Search for it, dig it out if its there using expensive and intensive methods.
Pump it around the world via ships and pipes.
Get it refined, and then driven around the country, put into holds.
Then sell the stuff on forecourts.
How many people are involved/paid in that process – i find it astonishing that petrol is only 1.20 ltr. Bloody Coca-cola is more than that and that’s just some sugar etc.
