Two persons A and B have known each other for a while. A is interested in B's life. One day, A gets up the courage to ask B a question.
A: Can you tell me about your life?
B: You got three hours?
A: Yes, I do.
I can't change the boldfaced sentence to the following:
B: Will you have three hours?
This is wrong.
But if I add the word "now"? Does it work?
B: Will you now have three hours?
