I think what the OP is really objecting are FAs who think that their ONLY job is safety. "I'm here for your safety, I'm not here to serve you a glass of water".

Safety takes priority over comfort, that's pretty obvious. But when there are no doors to check and no emergencies to attend to then the FA's job is attend to their customers' comfort.

Slightly OT (but sort of relevant) - some years ago I encountered a cabin crew member who seemed to think that his company's profit come before both safety and comfort. I needed medical assistance. He said "I'll be with you in a minute" and carried on with what he was doing - handing out bar price lists!
