Customer Service 101

So I bought a video game today (I know I'm a dork, deal with that, let me tell my story), and when I got home, I realized the guy had put the empty display case in my bag instead of the new game. So I went back, with five minutes to spare before the store closed, and the door was already locked. I held up the empty case at the guy through the glass, and he laughed at me and gave me a mocking "there's nothing I can do" face. When I gave him the "it's simple, it'll only take a second" face, he laughed at me, and turned the other way, completely ignoring me. Suffice it to say, this pissed me off, especially since that was the guy who had just rung me up.

So, in conclusion, to all my friends in the retail industry, here's an easy to remember list of three things to never do when you work in customer service and an irate customer approaches you:
1.) laugh at them
2.) refuse them entry into the store
3.) turn your head and pretend they aren't there
