At the risk of stating the obvious, social interaction with our fellow humans today is fraught with complications. Those challenges can trickle down to every aspect of our daily lives, including public places, many of which are staffed by hard-working and often underpaid employees. The rule about treating others as you'd like to be treated doesn't end when you walk into a bar or restaurant or supermarket. And yet, some still appear willing to annoy waitstaff by asking for a table 15 minutes before closing time or snap their fingers or make other rude signals you should never make at a bartender.

Case in point: A post on a Reddit thread (aptly titled, "why do yall do this? why can't yall put stuff back?") highlights a particular strain of customer behavior that involves taking a perishable item like meat or dairy for purchase and then changing one's mind about it. Rather than return it to its temperature-controlled environs, some customers leaving the item in a grocery aisle or elsewhere to spoil.

Judging from the heated posts on the thread, this thoughtless decision seems to be one of the best ways to get Sam's Club workers to hate you. As one Redditor pungently put it, "By the time we find this s-t it's bad. I'm zoning right now" -- zoning refers to the placement of goods to enhance customer sales -- "and it's already f -- -g bad. Waste of food."
