You are in the barber’s you want to ask the barber if you have to wait long. What would he say to you?
I don’t think. I’ll cut your hair, if so, don’t wait any longer.
Shall I wet your hair or shall I comb it dry?
Waiting so long doesn’t make you bored whenever you’re still reading book?
No, sir! There’s only one ahead of you. Won’t you take a seat for a little while?
