Salesperson: Can I help you, Sir?
Will: No thanks, I'm just looking. Well, just out of curiosity, how much is that necklace?
Salesperson: Twenty-nine, ninty nine.
中的20,99是什么意思?
Salesperson: Cash or charge, Sir?
Will: Charge, please. Do you accept Discover?
Salesperson: Yes, we do.
Cash or charge付费还是记账。西方买东西记账什么意思?是用信用卡吗?
