Have a furniture store in the small downtown area of my town. The entire building looks cigarette stained. They have brown tint on their windows, and peering inside, all the furniture looks crazy old and probably not something you’d want to buy.
On top of that, they’re open “by appointment only” and that’s just about the only sign they have other than the name of the business. Never seen anyone go in/out. It’s in a major location too, “Main street”, there’s no way it’s a real thing.
Is there a business in your town, which you are 100% sure is a front?
