A guy walks into a bar, goes up to the bar man, and says “Can I have a pint of beer and a packet of helicopter flavour crisps please?”
The bar man looks at him confused. “I’m sorry?” says the bar man.
“A pint of beer and a packet of helicopter flavour crisps please” The guy replies.
“I don’t understand” the barman says, still confused.
By now the guy is starting to get angry. “Look mate! Are you the bar man here or not? All I want is a pint of beer and a packet of helicopter flavour crisps!!”
The bar man, still confused replies “Right, the pint of beer is no problem, but helicopter flavour crisps? I’m sorry sir but I have never heard of them.”
“Oh! forget it then, just give me plane ones instead.”
