Great customer service is generally marked with a Wow by a customer; when you do that, you've won the customers loyalty. I was wow'd today, but not the way a store would like.
The point of sale is the most important part of making any sale, and when you put someone in charge of the point of sale that flunk out of 3rd grade you just wow'd me entirely the wrong way. It took us over 30 minutes to check out with two people infront of us in line. If it wasn't black friday and the two articles of baby cloathing weren't 65 percent off, I would have walked out.
