I have to go the grocery store tonight, and I’m already dreading it. The scene there is all too easy to envision, probably because it’s the one I encounter every time I go: aisles crowded with shopping carts and patrons standing in front of products with dazed looks on their faces; a sea of people in the express lane, half of whom obviously don’t meet the “ten items or less” requirement.

This undoubtedly rings a bell with most people, since annoying behavior seems to be a necessary accompaniment to the supermarket experience.

But why should this be so? If so many of us have the same complaints about grocery store decorum, or lack thereof, you’d think we might’ve solved the problem by now. I suspect the issue is that many of us are unknowing offenders, which means we could all use a refresher course on grocery store etiquette or how not to make food shopping an aggravatingly painful experience.

1. Don’t block the aisles and products. Grocery store aisles are never as wide as they should be. All it takes is a couple of haphazardly placed carts to create traffic jams. The solution’s easy: when occupying aisle space, make sure your cart’s pushed as much against the shelves as possible. If you’re trying to decide between two different brands, don’t stand in the middle of the aisle or directly in front of the products while doing so. That makes it hard for people to get around you, or for people to get their product of choice.

2. Parents, keep kids in check; non-parents, don’t judge kids for being kids. Children running amok in a store or screaming their heads off are liable to make me throw an inner temper tantrum of my own. I understand that parents need to bring their kids places.

But that doesn’t mean they’re not responsible for the kids’ behavior. I’m referring to unruly children specifically; kids who forget to use indoor voices or who act playful are just being kids, and the rest of us would do well to remember that, rather than glaring at their parents. We’re all just trying to get out of the supermarket with our dignity and sanity intact, and undermining others doesn’t help that one bit.
