Where petrol is cheaper than water

I had managed to work my way up to Puerto la Cruz on the north coast via Ciudad Bolivar, using a combination of whatever public transport or shared taxis that was available. I knew that petrol was cheap in Venezuela as at the border, there was a constant queue of Brazilian vehicles coming to fill up. The shared taxi stopped at a petrol station and filled it up with over 40 litres of unleaded fuel. He paid the equivalence of around one US dollar for the service. I didn’t expect it to be quite THAT cheap. I was thinking of petrol for the whole remaining journey.

-"Ay, Mike, are we at the petrol station yet?"
