Around 2003, I was helping a friend set up a new restaurant here in China and one day a woman turned up touting Apple Cider Vinegar for the bar! She spent an hour or more extolling its virtues and ability to cure everything except idiocy and gullibility. She got nowhere near a sale. I did suggest some good scrumpy or hard apple cider would do nicely, but she seemed unsure if any such thing existed.
Twenty years later, it is still on sale in supermarkets, so someone must be buying it, proving it doesn't cure gullibility.
