Taste the soup

A guy eating in a restaurant calls the waiter.
-Please taste the soup.

The confused waiter asks:
-Is the soup too hot?
-Just taste the soup...

-Is the soup too cold?
-Taste the soup.

-Is there a fly in the soup?
-Taste the soup!

The waiter, tired of guessing, gives up.
-Alright, alright, I'll taste the soup. Where's the spoon?
-Aha!
