Input: Text: this tifu happened to a friend of mine, throw away account because i don't want anything to do with this story.

only a couple of months after 9/11 my friend was checking in for a domestic flight in australia. signs all over the airport, including one on the counter right in front of him, stated terrorism is not a joke and any jokes related to terrorism would be treated as real.

so the person checking him in asks the obligatory questions, including "do you have any explosives in your bag?"

my friend/dickhead thought it would be funny to say "yes." he was laughing and smiling at the time but in light of recent events the lady obviously didn't find it funny.

he missed his flight, missed his trip, and is now a convicted terrorist which (can) restrict even what countries he can fly over.

he was warned.

TIFU by jokingly saying I had a bomb in my bag.
