Well I am pleased to say now we understand each other we seem pleasantly agreed.
What you would or wouldnt do is one thing (and I am sure you you wouldnt) but you recognise that others might. I think you also recognise that different flights and a different relationship with the client aka passenger brings with it different pressures some easier and some less easy with which to cope.
As to treating people with courtesy and professionalism that was never in doubt.
