Put it Back Where it Belongs
It’s perfectly okay for customers to decide that they don’t want something. Maybe you’re second-guessing your purchase or realize that you don’t have the money for it. But then, the courteous thing to do is put it back where you found it. If you can’t remember, there are plenty of signs in stores you can go off of.

What grocery store doesn’t have raw meat and snack cakes in the same aisle? Duh! Hopefully, you could sense our sarcasm with that one. This person clearly didn’t attempt to put this raw chicken back in its right place. Not only did it make a giant mess, but raw chicken is known to carry infections and funny smells.
