Is there a business in your town, which you are 100% sure is a front?

I have a shop near where I live in the middle of a suburb that only sells fans (the wind blowing kind) and they are a DHL pickup point, everytime I am there there is nobody there. The fans are stacked in boxes up to the ceiling and the quantity of them never changes, been that way for over a year now.

There is also always a shady ass person behind the counter, and often a few shady persons in the "back" of the store.

Since they only sell fans they should've called their store OnlyFans come to think about it .
