Coffee and a Fly

A customer ordered a cup of coffee in a restaurant! The waiter served the coffee. The customer found a fly in the coffee. He called the waiter.

Customer: How do I drink this coffee!
Waiter: Don’t you know how to drink a coffee?
Customer: Waiter, see, there is a fly in my coffee.
Waiter: Oh yes sir, you are right! There is a fly in your coffee.
Customer: Waiter, I said, there is a fly in MMY coffee (He stressed the word MY)
Waiter: Oh don’t worry sir, the fly won’t drink much!
Customer: Waiter, it is swimming in my coffee.
Waiter: Sir, do you want me to get a lifeguard for the fly sir?
(Annoyed) Customer: the fly dead, it’s irritating!
Waiter: I guess, it doesn’t know how to swim properly.
Customer: How do I drink this coffee?
Waiter: Don’t you know how to drink? I will teach you!

He drank the coffee! And said, this is how you should drink a coffee.
