Pax can be as rude to you as you let them. Grovelling at their knees in prescribed Ek manner will only encourage them to do so. Acting like an adult will not.
If they hit you, that is grounds for restraint, and any purser/captain ought to know this and act accordingly. Any who let pax assault their crew has no business being in their position.
Crew managers get paid very similarly to Pursers, but with a better housing allowance, thats all.
They earn this money by telling crew ethey are unavble to assist them in any way shape or form, that they have their hands tied, although they would like to know why you had so many sick days (6) last year.
They are more commonly known as CSI's - Crew Sickness Investigators, as this is their only posssible function these days.
CSI Dubai -whhhhoooooo are you? whhhooo-oo whooo-ooo?
CSI Grisley is on the case, a crew member dared call sick. Check for finger prints on the phone's 2 button. Check for GSR (Going Sick Regularly), check for semen stains - good god, how did they get on the ceiling??????
It looks like Horatio Cane will have no choice but to delay your upgrade (don sunglasses)... indefinitely.
