@georgetakei I work in a small local grocery. This is exactly how Americans treat any store they enter. I've also worked in retail auto parts stores and big chain supermarkets. Everywhere I shop, other shoppers have gone before me leaving a trail of opened and half consumed food, melted ice cream they decided they didn't want after all, opened soft drinks on shelves next to clothing or pet food displays… on and on, ad infinitum. Every behavior listed on the sign and more. I could go on, but I'm starting to whine.
