without audio and video we'll probably never know. Seems to me, if someone says something to me like "Take my wife to jail, she stole my happiness" I can conclude it's a joke. Or , "I didn't do it officer", another common joke. In my decades of policing I've never come across an employee at a business that said "we don't serve cops". I would imagine IF that were to happen, the person would immediately feel compelled to demonstrate it was a joke either by laughing and saying "Just messing with ya" or some other sign they weren't serious. In this current environment I wouldn't find it too hard to believe someone would be anti cop enough to make that statement. Then later it was down played as a joke. In other words, I think It would have been pretty clear to the cop at the time if it was a joke or not. If it has to be explained later.. then it probably wasn't.
