Of course it's important to keep in mind that 99% of the people we encounter in the grocery store are behaving quite well. It's even possible to witness acts of great kindness and civility. I once saw someone pay for a stranger's groceries (express lane) when she realized that she had forgotten her wallet.
And it's important to remember that we're all probably guilty of grocery store misconduct at one time or another. Grocery shopping can be stressful, especially if we're pressed for time or are dealing with money issues or just having a really bad day. So as much as we want to start yelling at the clueless shopper who is blocking traffic in a busy aisle, it's probably best to just take a deep breath and then another and say, as cheerfully as possible, "Excuse me!"
