My ex once tried to take circular saw blades in his carry on luggage on an international flight.
He called me to come pick the blades up from the airport so he could catch his plane.
When I got there, the security guards with him just rolled their eyes, to which I responded, "there's a reason he's my ex husband".
We laughed.
That doesn't have much to do with this thread except for people being dickheads in relation to airports.
