At a two-day dawn raid of the EU Commission in Munich, the team found on the second day that one seal on a door was broken. What did the raided company not (!) state as an explanation for the broken seal?
Exhaust air from the company cafeteria on the floor below
Overnight polishing of the door by a cleaner
Vibrations from slamming the door of a neighbouring room
High humidity (80 %) in Munich on that night in May
