I was at Schiphol airport the other day with my big Bose over-ear noise cancelling headphones, minding my own business and listening to some good tunes while waiting in the security queue and suddenly I turned a corner and there were these ultra-direcional speakers that cut straight through my noise cancelling headphone sound and started telling me what to take out of my bag. It was extremely confusing, I thought the music track was corrupted or something 😵‍💫
