A(柜台小姐)：Hello,this is Nike.Can I help you?
B(顾客)：Yes please.I would like to get a pair of new shoes,but I'm not quite sure which kind of shoes I should buy.
A：OK,so would you mind telling me what do you buy these shoes for?
B：Yeah,sure.I just started a running plan lately,but my feet were really hurt when I wore my old shoes to run.I just wanna buy ones that are maybe better for running.
A：I see.Actually we do have a kind of sneakers that are specifical for running.Let me show you where they are.
（带顾客去跑鞋的位置）
A：OK,these are the ones.
B：They look nice.Can I try one?
A：Absolutely,what's your shoes code?
B：I'm a 41.
A：OK,wait a minute please.
（小姐去拿鞋子）
A：Here you are.
（顾客试鞋）
B：Um...You know what?These are a little small for me.Are they really 41?
（小姐拿起另一只鞋看了一下号码）
A：Yeah I'm sure.Oh.I'm sorry.I forgot that these new shoes used a brand new standard sizes,so they are a little smaller than the original ones.I'm so sorry.
B：Don't worry about it.
A：Let me get a pair of 42 for you.
（小姐去拿鞋子）
A：There you go.
B：OK,these totally fit.I'll just take these.
A：Thank you,and again I'm so sorry for my mistake.
B：It's really OK,and thank you for your service.
大概就是写一个顾客想买跑鞋,小姐给他试他穿的41号的鞋,但是忘了新进的这批鞋尺码都偏小,因为它们用的是新的尺码标准.然后小姐道歉,去拿了一双大一点的就整好了.
不知道是不是写的长了一点
