I don't want to serve coffee... or apply application hotfixes (stuff more typically "administrators" or "ops")... but at my pay rate? I'd do it and question why I'm getting paid $$$$$ to do something that $ can do.
I think you risk "why are we paying $$$$$, isn't that the guy who serves the coffee" even if it's subconscious.
But my attitude is more along the lines of "I'll do what it takes to get the job done" and that attitude comes from my veteran experience - there was no shortage of times where the NCOs (mid level enlisted) would get "dirty" when a job has to get done...
You can see it as "why is that person relegated to nothing duties"... I see it as "that guy is part of the team and will get the job done, no matter what".
I do get your point and can see how "office politics" can spin things that way.
