What's with the Attitude?

So I went to Harmon's today to get my vegetables and I just love everything about Harmon's. I found all the veggies I was looking for and more, they were fresh and crispy, etc. I spun around to the area where they sell the Cuisinart appliances and other kitchen gadgets and struck up a conversation with an employee about cooking a roast. That led to pressure cookers, then to coffee machines and inevitably life. She offered wonderful customer service, but then again I just expect this from Harmon's. So at last my shopping trip was over and I headed for the checkout, I chose the shortest line and browsed the tabloid magazines until my turn. Well I'll be if I didn't get a checker with an attitude! I'm always very polite; however I give them a chance to greet me as it's in their job description. She had a bad attitude at go and I was so disappointed...she didn't even ask me if I wanted stamps or ice. I'll give her one thing though; I got my bag credits without asking.
