My partner and I ended a great trip through Brussels and Amsterdam in Munich and were appalled at the rudeness of literally every single person we interacted with. Vendors seemed annoyed that they had to bother selling anything to us, metro operators wouldn't help direct us to ticketing kiosks and then threatened to fine us when we didn't know the protocols, and an old couple literally sat themselves down AT OUR LUNCH TABLE (it was not a communal table) and tried to light up a cigar. We will obviously never be coming to Munich again or spending another cent to people who clearly didn't want us there, but we were so confused by this behavior we wanted to ask people who might be able to explain. If it matters, we are a male/female white American couple in our early 30s who were dressed well and only trying to eat/drink/enjoy our brief time in Munich. Never again.
