I have been to several stores in the area and there is always room for improvement. No store is going to be perfect, and surprisingly despite being in the hobby for a long time, you can always learn something new.
What's important is that instead of faulting our local stores is that we address (I recommend carefully and politely) the owner or management with constructive criticism.
I'm glad you can go and read any article and sound like an expert on HLLE bluerug, probably an article like
http://reefkeeping.com/issues/2005-06/sp/index.php, but lets say you had 30 years experience in this hobby and have owned or worked with several tangs over these 30 years. Despite scientists not doing conclusive studies on such a thing doesn't mean that simply just through trial and error most cases of HLLE are truly caused by diet difficiencies. Every fish I've seen with this is usually on the wrong diet for its species and very quickly recovers when put on the right diet.
Some people who run or work at a fish store may not have this experience or may not know it. Perhaps its cheaper to make up a batch of food all at once at a store and feed fish accordingly - if someone mentions that its easier to get the proper nutrition to fish by feeding the veggie type foods first, hungry fish will eat it up and will get the nutrition they need if they are omnivorous or herbivorous. You just can't assume everyone knows the same amount of stuff about fish - in the business or not.
That's where a club like ORCA should come in- everyone will always have their store preferences but if you do see something that seems off, my guess is store owners would be willing to listen if you were able to voice your concerns in a constructive matter.
My personal pet peeve is when a fish expires (which from time to time they will in a store. Shipping is very stressful as is being in a small holding tank) and the store leaves said fish in the tank. I think stores look healthier and cleaner without these mishaps on display. If I'm ever at a store and see this I try to point out that "um, you seem to have a dead one

" or something to that effect.
Also I know living as far away as you do Jason you probably dont go out to too many stores, but there are a few on the central and east side of town that I see selling yumas for pretty much the same price and even the ones I've taken a drive to out to the west and south.
Don't forget most stores can usually order something in if you don't see it if you just ask
