Years ago I worked with a contractor demolishing a Chinese restaurant. The upper floor of the place had been used as a kind of dormitory with folding beds and discarded clothing. It was clear there were illegals living above the dinning area.
The boss told me he’d demolished a couple of Chinese restaurants and found the same thing.
An Asian “massage parlor” was recently busted in Rockland, Maine. My home/auto insurance agent was involved. Make that, my former insurance agent.
