I agree with the general point Gilmore was making, just not the way in which it was made.
His actions have helped no one. We all know exactly what the situation is like at the moment and he must have been well aware of the consequences of his actions. How very selfish to make an aircraft return to the gate just because he was trying to make an issue of it.
I agree with the Captains decision; after all this wasn’t about the "pin" but rather Gilmore’s attitude, which was clearly one of arrogance. I would not like to have taken this potential problem in to the air and had to deal with his lack of co-operation in front of other passengers. Other people had also paid money to board that flight and were every bit entitled to an uneventful journey as Gilmore.
