In a Bar

A man entered a fancy bar and took a sit. The waiter passed by and asked:
- What can I get you, sir?
- Nothing, thanks! Once I tried alcohol and did not like it. Since then I have never put a drop in my mouth.
The water felt puzzled a bit but he was a friendly guy and offered a cigarette to the man. However he declined this offer as well.
- Once I tried smoking and did not like it. Since then I have never put a cigarette in my mouth. Look man, I shouldn't be here but I have a meeting with my son.
Then the waiter replied:
- Your only child, I guess?
