I've seen roaches, and glass (1/4" cube piece) in food. Mostly Chinese restaurants.
My wife and daughter, grandson and I had lunch in a hole-in-the-wall Chinese restaurant here one Saturday.
While we were eating, my grandson, who was just about 3 at the time hit the aluminum window frame next to our table with his fist for some odd reason.
All of a sudden, thousands of roaches came pouring out from underneath it!
Just like that scene in the movie ‘Health Inspector’ with Larry the Cable Guy where he kicked the toe-plate under the counter............
