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

We have a Mexican store here (one of several), but people come from ~90 miles to come to THIS one. None of the others in town, just this one. There’s a ton of others between here and there but this one is special. It’s not fake documents because I know other places that have those.

Not sure what they’re doing but they’re always busy and a ton of out of town/out of state people come and go.
