The picture is completely illegible, only the initial first few lines can be read, the smaller text is just a blur is there a link where it can be read?

Edit Never mind I found it on line.
First a knights cross, aka the iron cross is not a Nazi symbol but I suppose they were both too dumb to know that. Ironically it was first awarded to soldiers who fought against Napoleon's imperialist forces
Second if you have a notice saying so, an establishment is perfectly entitled to refuse service to whoever they like for whatever dumb shit reason, even if it means turning away paying customers.
Third the barman sounds like the sort of arse who would turn out a guy in a shirt he does not like but would allow in some fat turd in a combat uniform and confederate flag carrying an assault rifle and call that fuck a patriot.

As an unabashed liberal, I can tolerate most opinions with one exception, Nazism. There is no place for their intentions in a civilized peaceful world. Their very doctrine requires the most abysmal abominable practices which have no place on the planet....perhaps universe. They would implement tyranny as a form of people control.

And that is exactly how I feel about Russia Today, Putin the Poisoner & other Nazis. Not one millimeter.

You've got to know your clientele and who's trying to infiltrate it. Could this bartender do the same thing to other folks who's lifestyle he doesn't approve of? Ask it that way and it becomes murkier.
