Two men on a train

Two men are sitting next to each other on a train. One is an older business man who is going over his accounts.
Occasionally he looks at his watch on his wrist
The other is much younger and is wearing threadbare jeans.

After some time, the young man asks, "Excuse me, could you tell me the time?”
The older man says nothing
“Excuse me again, but could you please tell me what time it is?”
The older man looks out the window. Then he looks at the younger man
and says “No!”
The younger man is quite irritated by this. “Look I asked you a perfectly reasonable question. Why won’t you tell me the time?”
The older man replies, “If I tell you the time we will start a conversation. You will learn things about me. You will find out I have fanciest restaurant in Toledo, that I have a beautiful unmarried daughter. You will come to visit us. You will fall in love with my daughter. You will marry her…”

“Well, would this be so terrible? I am a perfectly respectable young man.”
“Perhaps,” says the older man “But I don’t want a son-in-law who cannot afford a watch.”
