This isn't political but I guess not politically correct, and I don't mean to insult anyone, but what the Chinese eat a lot of it is really nasty especially meat. They eat dogs, horses, etc.
We used to patronize a local Chinese buffet restaurant, seemed like great food at a good price. They were always very busy.
A few years ago my wife and I sitting near the back, a warm summer day and they had the back white painted wooden door opened a bit.
Now this next part anyone who owns cats or been around them knows this is true...cats love to rub their heads on a door or corner. Our house I have to clean those dark spots, they start about 6" up from floor go up another 6".
This restaurant back door had that spot!

Wife agreed it was cat marking. Next day I called the local animal control. (Restaurant was next to a large sub division). I asked if they had lots of reported missing cats from there? "Yes"!

So I called health department. Lady said we'll check it out...let you know our findings in a few days.
I never heard anything so I called them. I get this nervous...oh, everything was ok, answer.
We ride by the restaurant and they were shut down! I never got an explanation.
