顾客至上,锐意进取 如何翻译

英语翻译
One morning,I met a customer(顾客)in my shop.He wanted to buy some new clothes.First,I gave him a pair of trousers.He put them on to try,then took them off and gave them back to me and said,“No,give me a coat instead.”
I gave him a coat and told him,“This one is worth as much as the trousers.” To my surprise,he took the coat off without saying a word and walked out of the shop with it.I ran quickly after him and said,“You haven’t paid for the coat!”
“But I gave you the trousers for the coat.”he said,“They are worth the same as the coat,aren’t they?”
“Yes.”I said,“But you didn’t pay for the trousers,either!”
“Of course,I didn’t ”answered the man.“I did not take them.I am not foolish!Nobody gives things back and then pays for them.”
