46. 标准买单方式
当顾客问你：“How much will this be”(多少钱?)，你可以说“Just a moment, please. I''ll calculate that for you.”(请等一下，我算算看)
47. 解释税率及服务费
顾客的疑虑多针对服务费service charge(在国外还有税率tax rate)，您的说明一定要明白无误：“A 10% service charge have been added to your bill.”(账单已经加了10%的服务费)
48. 如何议价
如果愿意降价，可以使用however来转折语气：“However,..., we can give you a discount.”(然而，由于……，我们可以给您打折)
49. 如何优待熟客
对熟客可以说：“Ordinarily we sell them for one hundred and fifteen dollars, but I''ll make a concession.”(我们一般要卖115元，但您可以优惠)
50. 如何给新顾客打折
对新顾客可以说：“I can manage to give you a discount of ten percent, deeming it as a kind of expenditure for advertisement.”(给您9折，当作是宣传费吧)
