A: Excuse me, sir. How much for this lamp?
B: I'll sell it to you for $50.
A: Oh, no! That's way too expensive.
B: What price did you have in mind?
A: Maybe something closer to one fourth that much.
B: I might as well give it away for that price!
A: What about half?
B: That's still not enough of a profit.
A: I'll give you $30 for it.
B: Make it $35 and you've got a deal.
A: Alright, that sounds good to me.
B: You sure drive a hard bargain!
