Just popped in for a quick visit:
Comeflywithme - guess that if you really don't give a s--t at 0300 your attitude is reflected by people like XTC who find briefings very boring.
If the CSD does't give a damn it is well reflected in the rest of the crew and sign of very bad management on board the aircraft.
Some crew have the experience to be well rested and fit to fly at any time - basically reflecting the reason they are employed - brief a crew well - have a good rapport on aircraft and all crew and passengers can go home happy! Service industry at its best I guess!
On the subject of not being able to tell a passenger you are annoyed with them - a little thing that comes with maturity and experience - can be expressed in very nice manner and both come out friends hence good service and passenger that returns.
Positive attitude can count for a lot in life.
XTC may be a 100% person for passengers in your eyes but in other airlines may only measure up about 30% in attitude towards work and consideration for others which is a very important quality in life.
