Had a bunch of drunk Swedes on a stag party to LAS once, causing general rudeness, demanding more booze because they paid for upgrade, trying to vape etc. The lead told them last chance or they'll be meet by cops and you'll spend your weekend in Las Vegas locked up. They finally fell asleep and when awoken on arrival apologized and went on their way. Walking out of the airport the groom ran up to us and explained he couldn't find his passport! Karma? Sorry man, if you hurry back to the gate you might still find the gate agent who can search the plane for it, good luck jerk.
