要是一位顾客订了特别大的一批货，帮了我的忙。

You got an extra hint here in terms of the order, so even if you had just forgotten what I said, sometimes it's not a terrible idea just to put it in the order it's written, that can give you a lot of clues as well.
其实大家还可以发现一个额外的提示，因此即使你忘了我刚才说的，有时候直接按照这个顺序,排列也不失为一个办法，这也可以给你很多提示。
