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!
