Does this "will" denote the present or the future?
24)One day during a lecture tour, Mark Twain entered a local barbershop for a shave. He said to the barber that it was his first visit to the town. "You've chosen a good time to come," the barber said. "Mark Twain is going to lecture here tonight. You'll want to go, I suppose?"
"I guess so..."
It refers to the present and future (up until the time of the lecture) as at the time of speaking.
If I said to you in the present, "You'll want to go, I suppose", it means that I suppose that, at some stage between now and the time of the lecture, you will decide that you want to go.
If it relates to something you already know about, it tends to refer to the present, since you should already know whether you want to go or not.
