Once there was a man who was very fussy about food. One day, he felt like having some seafood and went to a restaurant and ordered some oysters.
The man said to the waiter, "Please check that oysters are neither too large nor too small, neither too salty not too fried, neither too fat, nor too thin."
At this the waiter said, "Do you want them with or without pearls?"
The man realized that the waiter was taunting him and understood that one should not be so much fussy about things.
