Dutch people speak English flawlessly. It’s almost annoying. You’ll arrive, say “Dank je wel,” and they’ll reply in perfect British-accented English. It’s because the Netherlands is the most English-proficient non-native country. You can’t even secretly practice your vocabulary; they’ll switch to your language to save time.
But here’s the fun part: Try to order a beer. Say “Een biertje, alstublieft.” They will smile, impressed. It’s like a secret handshake.
