A man walked into a restaurant that advertised having the longest menu in the world.The manager was very proud of being able to provide any dish,no matter how unusual.
At the bottom of the menu,there was a notice that said,“If you do not see the dish you require on this menu,please tell us and we will add it to the menu immediately.”
The man looked at the menu and decided to make life really difficult for the manager and his chef.He would order something that was very unusual.
When the waiter came up to take his order,he said,“You say you can serve any dish,anything at all,even if it''''s not on your menu,which is the longest menu in the world.”
“That is correct,sir.We have never yet been unable to meet our customers'''' requirements.”
“Very well,” the man said.“In that case,bring me two elephant ears on toast.Indian,not African.”
The waiter wrote down on his pad：Two Indian elephant ears on toast.
“Very good,sir”,he said.“That shouldn''''t take long.”
He walked away quickly.
The man was very surprised and rather disappointed.
Then he smiled as the waiter returned with a very unhappy look on his face.
“Ah!”the man said.“You can’t bring me elephant ears on toast,can you?”
The waiter was very apologetic.
“I’m very sorry,sir,and this is most embarrassing,” he said,“but I’m afraid we can’t.Unfortunately,we’ve run out of bread.” Why did the customer order elephant ears?(本题分数：4 分.)
