Ya know, this is true, but not really in the 135 world at all. In 135, you do everything at many jobs, because most of these companies (including Mokulele) are small-ish businesses. You're the ramper, you're the gate agent, you're the pilot, you're the flight attendant, and you're the dispatcher in 135. This is especially true, "off the beaten path" like in Alaska. You're not going to remain employed very long if you don't help load and unload your airplane up north. Can't speak to the way it is at Mokulele, but even here flying medevac in Hawaii I'm helping load the patient, I'm filing my own flight plans, and between legs I fuel my airplane and replenish medical oxygen. That's simply a part of this job (and it's not something I mind doing).
I will also say, that in defense of OP, it's not really fair to say, "hold your standards high, don't throw bags," when you've got less than 135 mins. Hell, I'm a 6,000hr pilot and I've thrown bags and fishboxes, and (THE HORROR!) helped load and unload other pilots airplanes from time to time when we were slammed at most jobs I've been at. I've never had a job in aviation where I wasn't somehow responsible for things outside of simply operating the airplane.
Let me put it this way, if it were my company, who would I want to hire? The guy who helps out when needed and goes the extra mile when other people need a hand? Or the guy who says, "that's not in my job description" and walks into the pilot lounge to put his feet up. Personally, I know who I'd want to hire. It's not like he's crossing a picket line, he's helping unload airplanes that he's flying! I don't see the problem with this at all.
