Well, in Finland we have a saying: "Name does not put shame on a man, if the man doesn't put shame on his name".

So, by using the word "pig", meaning the Police, your friend did not shame the Police. He shamed himself and made himself a "rightful" object of disrespect and laughter. One can be shamed only by his own words (and doings), no-one else can do it.
The landlord might want to make business with people... People tend to avoid places they do not feel comfortable, and quite many do not feel comfortable at a presence of a person publicly showing disrespect to other people or a group of people. And yes, if the words were heard by some other customer, then it was publicly spoken.

Well, different country, different traditions. No offence meant but this is how I see this story of yours. And you asked to see comments.
