There's a furniture store that is never open that I go by a lot which I find odd, but I don't know if it's shady. We literally do have Mafia in my city though.
You just reminded me of one store near my workplace, it sells tableware and rather pretty so I asked them what's their schedule and they just said that they don't know ¯_(ツ)_/¯ how are you even a business if you don't know when do you start and finish your work
That's really strange. Like why have a store? This place is office furniture so maybe it's just occasionally used as a showroom but I go by several times a week and have never seen it open.
