Ah, how I wish I were one of the "most professional men and women in the industry" (RAH RAH!) working that flight so I could have given her the choice of continuing her attitude and complaining to the ground staff as the flight left without her, or shutting up and taking the water and the crappy headphones and being happy with it.
And before you even start channa and other anti-CO, anti-crew apologists- nothing- not the fact that you are the customer, and certainly no amount of money you allegedly spend with the airline- gives you the right to treat me or my coworkers with such tackiness and disrespect.
Passengers have got to learn, and I take pride in putting my foot down and assisting them in that aspect.
