B.S.
Before a flight, a highly paid (given what they do) security theather monkey tried to demand that I forfeit an expensive bottle.
Knowing full well how it works in most countries, where the loots are split at the end of the day, I said "watch this", chugged it down, and voluntarily surrendered the now empty bottle.
At least I enjoyed it partly!
Even if later I did throw up during the flight, I prefer being sick than my luxury bottle being stolen by a security theater monkey.
