30. Just Learn German
When my mom was on vacation in Greece (years before I was born btw) there was a couple who were crying about how the people there don’t understand/speak German. In GREECE.
My mom was actually embarrassed (to be German?) and said sorry to the owner of the shop they were in. But the whole thing had a funny twist: turns out the shop owner could actually speak perfect German. She just pretended she couldn’t understand the couple to annoy them.
