Rome, Italy. rent for a small store is 800/mo where this store is, and an average salary is about 1200/mo. This antique/junk store sells like 2 things a day(with average price being 5€) always takes unfavorable exchanges and generally isn’t great business-wise, yet it’s been here for 15 years, in a district where most - more reasonable - businesses fail within 2 years.

It doesn’t take credits cards, only cash. There’s a flight simulator controller from the 80s that didn’t sell for a decade.

Maybe I’m just paranoid.

Edit: i still love that store, I’m addicted to collecting old junk (self promotion time: I founded a coin collecting community over at lemmy.ml,its called numismatics) and I go to that store every month or so, it helped me to get rid of some old vynil records from my grandfather in exchange for some cash (obv without receipt) but still, I think it either evades taxes (taking that from granted) or it’s something bigger, like a front for a mafia or something else.
