Yes. Like the check in attendant at PER, who just went and did the little things, like saw my boarding pass was knackered as after a long-haul international and with a smile, printed me a new one.
Little things like that, that make (or break) people's day. Like the QC staff in SIN, who gave me Panadols, because I was feeling lousy after a red-eye PER-SIN trip. For everyone who has ever gone the extra mile, or done something that has just made me say "Wow, that's nice", I always send a letter to their boss and tell them just what a good job they did.
It might be nothing to you, but to the valet guy, to the waiter, that might be the pat on the back that gets him to be the top manager one day. And to be told "Hey, this customer sent a letter and told me about you, and you did well" is nice for anyone to hear.
Shillard is right, in that, we have a good airline (even though it may be inconsistent in some ways) ; go on some other carriers and you'll see what rickety planes or bad service is like. Try Canada 3000. By the time the luggage came off the plane (30 minutes later) at YVR-MAN, I lead the round of sarcastic applause that engulfed the terminal because it was finally off the plane.
I say inconsistent, because sometimes, my luggage has been earmarked PRIORITY and it's QC tagged, and it comes off with the rest of everyone else's luggage. ADL is a favourite for this. QF managed to lose 15 kilos of scuba gear on a flight to Vanuatu one year too, so, so far, I've had BA and QF lose my bags (but I have been reunited with them and their contents the next day, so I'm happy).
In LAX, it came off on the wrong carousel - I was waiting at the F/J carousel (where the priority baggage was said to come off on), and instead, ALL the baggage ended up together !
