We suspect that there's a story behind this outfit, and we can probably guess what it is. During peak hours at Walmart (the kind you always have to avoid, but all of us have to endure occasionally when we need something immediately), we all know what it's like to have someone walk straight into us without looking where they're going. That can be a shopping cart in the ribs, a motorized cart in the shins, or just someone's shoulder or elbow carelessly bashing into you. It's a constant cause of shopping rage.
This is a woman who has, presumably, endured that experience once too often. She's decided she's never going to have it happen again, and so she's making herself as visible as possible to anybody who's crossing her path. We think she could probably have achieved it just by wearing the high-vis yellow, though. The crude question printed on the back is overkill, and makes us worry about what might be on the front.
