So up to possibly 170+ other pax (guests) were able to accept the fact that their ticket did not include water, blankets, pillows a bottle of Dom or a foot rub.
I don't know of an Airline Captain anywhere in the world who would call the police on a pax for simply asking for water. So what really happened? Sounds to me like a Flight attendant was cornered in the rear galley; Aggressive posturing and threatening overtones?
The fact that crew had quarantine issues is entirely irrelevant to the complaint and smacks of desperate character assassination.
