...I have to say, this picture is a bit contradictory.
For one, Islamist ideology tends to suppress public entertainment and lavish events. So this is already a massive deviation from that line.
And then the guy is wearing traditional Bavarian Lederhosen, so he's making an effort to culturally integrate.
With the cringiest segment of the population, but still.
Also, Germany is actually very fond of its high quality natural mineral waters, which are enjoyed in great quantities.
So... the most egregious imposition on the existing landscape there would be the ugly "I'm an Afghan farmer" hat.
