Describe how you have gone out of your way to exceed a customer's expectations?

There are many ways that you can describe how you have gone out of your way to exceed a customer's expectations. Think of a time that you gave great customer service and describe that time. Perhaps, you helped a customer choose a better item than the one they were interested in. Or you may have alerted your customer to additional products that they would need to put together an item, and helped them find them.
