Flight attendants are used to many different passengers, but there is a special place for those who try to smuggle things on the aircraft. It may seem ridiculous, but it happens pretty frequently. Flight attendants have only a few seconds to assess each individual while greeting them and trying to remain comforting and pleasant. In that small moment, they have to scan them for many things, and occasionally they get a weird person behaving suspiciously with their belongings.
One flight attendant shared, "I've had people try to smuggle pets in their purses or handbags, bottles of booze in their briefcases (booze is allowed as long as it stays capped)."
