Not so much a weird thing, but more a weird price.
My local thrift store are known to have high prices. Not because they sell high-quality stuff, the prices are just high. The most insane thing there is what’s clearly a jar that used to hold pickled beets. It’s clean, though, I’ll give them that. Pickled beets are cheap and available in all groceries here. The thrift store chose to price this, empty, jar at 150% the price of a new jar including pickles!
In Denmark it’s probably Snave (No English Wikipedia page for it). Population is a whopping 211 people. It was popularized in a series of commercials for a Danish cellular carrier. The concept was so popular that there even was a movie. I haven’t seen it, but the reviews seems to suggest it could be fun to watch… If you are drunk enough.
The word “snave” in Danish can somewhat be translated to snogging in English. Heavy kissing. Which has led to the city having massive problems with theft of their signs.
