No, Thank You
A well-dressed gentleman entered an upscale restaurant in the East End of Manhattan, and took a seat at the bar. The bartender came over and asked, "What can I get you to drink, sir"?
The gentleman responded, "Nothing, thank you. I tried alcohol once, didn't like it, and never tried it again."
The bartender was a bit perplexed, but being a friendly, outgoing sort, he pulled out a pack of cigarettes and offered the gentleman a cigarette.
The gentleman refused, saying, "I tried smoking once, didn't like it, and never did it again. The point is, I wouldn't be in here at all, except that I'm waiting for my son."
The bartender retorted, "Your only child, I presume?"
