In my small town supermarket they have a soup bar. It's self-serve and they allow free samples. But, Free sample means samples as in before you buy soup so you can try a little sip to see if you like the clam chowder, beef and barley which has too much green pepper, or squash bisque before you fill the paper cup or the larger one with hot delicious soup.
It doesn't mean "free soup" to eat while walking through the store and not buying any soup after the sample is gone and then as if to add insult to injury, leave the empty ramekin with your sample tailings on a random shelf, sometimes even with a little plastic spoon and a used napkin, tucked behind a roll of paper towels or toilet paper or catfood on your way out of the store to stand in the parking lot and complain to other petty soup thieves about how "some people" get stuff for free.
