I had a secretary years ago who kept kosher, however, she made an exception when it came to Chinese food, "it's chopped so small so it doesn't count."

Then there are people like my wife and my daughter, no issue mixing dairy and meat or eating shellfish, but no pork. My wife won't even buy chicken sausage if it has pork casings and she grew up in a Jewish household where they ate ham. I'm an omnivore, I eat just about everything.
