I am leery of any of those reports, honestly. I heard from people first and secondhand who “saw” the owner of our subway “dancing in the parking lot” with his workers and speaking Arabic. Then I read internet reports about the same thing supposedly happening in a lot of different towns, always at a Subway. It turns out that the guy who owned the restaurant was actually Indian and nothing of the sort happened.
Fast food joints and hotel businesses also provide good cover for comings and goings of strangers, a good place for temporary employment.
Local lawyers are good sources for who owns what.
