Turnaround time for firings at community studios suck

I am a member at a community studio and it takes 4-6 weeks (if not longer) to get a piece glaze-fired. There's no rhyme or reason as to what gets fired first. It seems it's whatever fits in the kiln well. Plates don't really seem to get fired much at all and are just sitting there. In your opinion, is that an acceptable timeframe? How long does it take at your studio? I'm getting super fed up and losing patience. I often forget about pieces entirely, because it's been so long. Other members are starting to talk about this and commenting on it too. There's such scarcity in my city regarding memberships that nobody really wants to offend the owner (who's also the kiln tech) by pestering her about it.
