German here. A woman was starting to play loud music on her phone while I was sitting at a bakery having a cup of coffee, trying to relax from a bad morning. I opened Spotify, checked for this song: www.youtube.com/watch?v=PDBDtIOxUsI Every Maaaaaamaaaa I was singing loudly along. She lasted half of the song then fled the scene, even left her coffee on the table. My ears were bleeding, but it was worth it.
Fight them with the most terrible old people song you know in your country, be aware that it might hurt you too.
