A fellow pulls up at a petrol station in Gaza and asks for five litres of petrol.
The attendant replies they don't sell petrol.
"Don't sell petrol? What sort of garage is this? Well, check the oil for me."
The attendant says they don't sell oil.
"What? Top up the radiator for me then."
The attendant says they don't have any water, and that in fact the garage is just a front for Hamas.
"Okay, then just blow up my tyres."
