I'm literally doing the same lesson/question right now. I couldn't put it in 125 words because it really isn't that serious. I don't know why they ask for so many words when the answer is short and straight to the point. But what I put was:
It's good that she's doing what she's supposed to do, but its better to go above and beyond; why not try to sell more to the customers? If you have the opportunity to directly talk to the customer and have an influence over their purchase, than why not try to offer them other products to benefit the company?
Also, just a quick question, if you are using ignitia, do you like it?
Hope this helps!
