That may well be the case, but does that have to be a bad thing?
I'm usually a pretty content fellow on flights and on the long hauls am not demanding of this or that. If I want something I'll ask, or usually I'll take a walk to the galley area to check out the snacks that are out, or grab a drink, but I'm not ringing the call button 10 times a flight either.
I also am aware that the cabin crew aren't responsible for the soft product they're given to work with eg the catering. I've been served some shockers over the years, and some fantastic stuff, but short of someone screwing up bigly in the galley, whatever's there is not their fault. I am quite content to make my own bed in QF J - it's easy afterall and I can manage myself (and prefer to do so tbh) rather than need a hostie to do it for me (they can do it in F though lol). I guess sure that makes life easier or the crew, but it also makes it easier for me (in J, I mean).
I don't mean this next comment to be directed to anyone in particular: I don't see cabin crew as servants or at my beck and call all the time. They are doing a job. Mostly a reasonable to pretty good job. I see how some (thankfully a minority) entitled pax treat crew members at times and cringe and feel for the crew having to put up with such nonsense. If I can be polite, respectful and not too demanding and make their life just a little bit easier then why not? I'm happy, they're happier(hopefully).. win/win. Doesn't mean I sit there dying for a drink and not doing anything because I don't want to bother anyone either.. it just means showing some common sense and manners. Plus, I like to get up and stretch a bit, so wandering down to the galley, maybe having a quick chat or just grabbing a snack or water myself is just fine too.
