Here’s an example of how American Eagle sets themselves apart with customer service. As I went in to the fitting room to try on some clothes, the clerk pointed out the button on the right, which says Don’t worry, we’ll get it. If, while you’re trying on clothes, you decide you need a different size, just press the button. This alerts the clerk who comes to ask what size you need, then goes to retrieve it from the store.

This is great—it saves the customer the hassle of putting their own clothes back on, and running around the store to find the size they need.
