I live in, if not the buckle of the Bible Belt, it's at least one of the first holes. Some random woman came in (On a Sunday, to make it even better) and bought some random collection of crap that happened to add up with tax to six dollars and sixty-six cents.
She flopped down on the floor and started screaming and flailing and yowling about how we wuz SATANISTS!!! and GAWD was gonna get me for this!
I mean literally 'on the floor on her back, kicking and screaming and waving her arms toddler tantrum' Sadly, I didn't have a video camera, this being some years before cell phones basically existed, let alone became ubiquitous, as this would have gone viral on Youtube, I'm sure.
I ended up sitting on the counter watching her be an idiot and telling her that if she damages anything she'll have to pay for it too.
After a while, she wore herself out or figured out that I just thought she was an idiot and wasn't at all inclined to do anything about it, so she went and got a five cent piece of candy to change the price.
