Agreed.
I think, as far as crewmembers go, the airport is our domain and our comfort zone.
The passengers (except for the HVC's) are usually in an environment that they are not familiar with and what seems easy and obvious to us is all new and confusing to them.
I question that 95% of ANYONE talking loudly on their bluetooth really have THAT serious of issues to discuss. I mean it's not like a brain surgeon is talking an intern though a surgery or anything.
I am very thankful that I'm not the F/A that has to deal with the arrogant HVC's.....
I flew very wealthy people for many years. The older the money and the more comfortable they were in their own skin, the easier they were to deal with (some notable Hollywood types excepted). It's the pseudo-rich and new rich that get really annoying.
