I had a security guy that checked for drugs telling me "This is Germany, why don't you speak German!" when I told him if he could explain what he wants me to do in English. (put down my bag on the table and show my phone so they can check it for chemicals)

Yep, this happened. In Airport. International Berlin airport.

I didn't say anything because I did not wanted to be detained for longer and miss my connection flight. But WTF.
