Not an unknown event, particularly in that part of the world. If the refuellers do not accept the airline's credit you are down to Captain's Funds/credit cards/bankers drafts telexed via OPS/cash on board.
There are places in UK where certain cards cannot be used - it always used to be that INS would not accept Diners for fuel. Don't know now.
Not a nice situation to be in! Don't forget there were probably cash landing and handling fees too. And... to add to the nightmare, they could well ONLY take US dollars............
