Because she is a total muppet, BSmuppet. She has no idea what she is talking about and has the square root of
all experience in the job, yet preaches to those who have worked for the company and been in this business for years, telling them they should be grateful that easyjet see fit to employ them. At best naieve, at worst completely ego-centric and unable to comprehend anything beyond her own nose.
She'll make a great manager.
