None of us would tolerate this sort of shambolic performance in any other facet of life. Especially not when paying so much.
Sadly, this is aviation. The normal rules don't apply I'm afraid.
Aviation attracts 'characters' and it attracts people who are in love with flying and could never consider working in another industry. This means they rarely have experience of working in businesses outside aviation, where such a shambles would never be tolerated. To aviation 'lifers', this is normal.
