Don't Be That Guy at the Grocery Store

I am not the most perfectly mannered man nor do I claim to be. In fact, in the privacy of my own home, I have been known to fart, belch, talk out of turn, take the last bit of ice cream and not save any for anyone else, but outside my home in the public realm, I put my best foot forward. I open doors for people, I say please and thank you, I wait my turn in line.
I have been asking around just to make sure I am not way off base here and I have pretty much received a unanimous response. What is the question? If there is a line of people in a checkout at the grocery store, or any store for that matter and a cashier opens up who is the first person he or she helps? The answer: Next customer in line please. Not the guy at the end of a twenty person long line.
Recently I was at Costco and we had been standing in line for nearly twenty minutes. Although, all we had was a birthday cake we still waited in line amongst every one who had two baskets full of groceries. Suddenly, just when we thought we could not wait another minute a ray of hope washed over our faces. We were "Next in line" and it appeared that the check stand next door to the one we were standing in was about to open. We waited anxiously as the cashier prepared her workspace. We watched as she walked away momentarily to seek some final instruction from her manager, she got some change for her drawer and organized it in her till. Like a lion stalks it prey we watched for that golden lamp of salvation to turn on that said, "Check stand Open." We were so excited we could hardly stand still and just as fast as it took the light to travel to our eyes was a thief who with a blitzkrieg motion came crashing in from the back of line paying no regard to the "Next customer in line" policy. It was like finally winning the lottery only to have Uncle Sam seize the whole sum for failure to pay taxes for the past ten years. Not that I know this first hand, but I am sure it feels similar. Under normal circumstances, I would not say anything, but this time I felt compelled to say something before I even felt the feeling of feeling compelled. With out any thought I immediately went on the attack like a bear that has not eaten all winter long. I shouted, "Hey, Hey, Hey, what are you doing? Next person in line is not you. Do you not see all these people behind you? Where are your manners?" He had nothing to say. He just stared at me. Immediately to get me to be quiet the cashier pulled my basket forward and began to ring up our cake. The man was still staring at me. I asked, “Are you just going to stare?" and then politely I said, “You can stare all you like, but it doesn't change the fact that you need to learn manners." He still just stared. I am not sure, if he was shocked that he was called out for his rudeness, or if he wanted to kill me. I don't really care either way because I was in a big hurry myself and still I stood in line just like everyone else waiting for my turn. His time was not more important than mine was and mine was no more important than his was.
The moral of the story is don't be that guy folks. We are all in a hurry, but this does not mean that we don't have time to remember our manners. Take your turn not somebody else’s turn. Save yourself the embarrassment of being that guy who cuts in line at the grocery store.
