What's so "super" about these stores?

So typically I make it a habit to avoid places like Walmart. The same thing as anyone else, they move in, sweep competition, then jack prices, etc. That's not the point of this rant though! These "Super"stores really freaking piss me off. We'll start with Walmart and move to Meijer shortly thereafter:

I have recently bought a couple of watches that obviously come too big than needed. Also have an older one that needed a battery replacement. No hard task for a trained jewelry professional at any megastore, right? Since it was on my way home, I caved to my standard avoidance of such places and pulled in.
Well, apparently the new policy is "we only work on Walmart watches." Are you kidding me? Either way, its a customer, its service, and its profit! It takes all of 2 seconds with the right tool to take out a link in a watch chain and so long as you have the battery its a standard procedure to replace that as well! And look at it this way, if it breaks, and the person acknowledged that this is a possibility upon requesting repair, you can then sell them a new watch! In what possible scenerio is repairing the watch a BAD idea?

Now for Meijer: I took some photo's there to have them printed so I can hang them on my wall on Monday. 3 8x10's. There were NO problems with this situation at all, everything went well, I bought 1 hour pick-up cause they were cheaper, glossy prints, and when I picked them up, they looked great (and are on my walls, lookin good).
Fast forward not even a full 48 hours. Seriously, 2 days. I went in on Wednesday afternoon to print more pictures: 10 4x6s and 2 8x10s. Something seemed weird this time, like I had less choices, and at the end of submitting my pictures I realized that the 1 hour photo option was gone. Also, my 8x10s were matte prints, and the glossy option was also missing. I asked, and the lady said in the last 2 days, they changed their entire system. Aparently shipped off their "one hour photo" printers. Seriously? You're going to FORCE people to pay more, even when the print options are more limited?!?
I discussed this with the guy that sold me the prints and he agreed with me, not good business. Don't they realize that people who select 1-hour photo then turn around and shop their store for an hour? Don't they realize that people also buy WAY more if they have to wait an hour than their normal shopping list? Certainly the last time I'm utilizing Meijer for any photo needs.

These stores make the most unethical business practices their MO when they move into towns, but they don't make the smart business moves when it has to do with the day to day services and sales? Unbelievable...
