Businesses that are not consumer facing are often far less diligent about signage and advertising than people think.
You'd think one of the largest (legal) indoor grow-ops in my state is a shipping products manufacturer if you went by the sign on the building. The shipping products manufacturer outgrew the building and is leasing it to the pot business. There's a business near me that manufactures medical plastics. Before them the facility was occupied by a company making pasta. Neither has a sign out front. The only difference is the company name on the white box trucks changed.
