Why are most Walmart employees stupid? Why are most in retail food ignorant?

Can somebody tell me why it is that most people who work in food retail are completely lacking of any moderate amount of intelligence? More over are so damn arrogant that their prideful ways exceed even that of any centurian ancient Roman servant? Here's my thing, go into our local Walmart only because I really didn't want to venture out to say metro Utah just for some underwear, (side note; why is it that men wear undershorts or our unders are called under shorts and womens undershorts are called panties?) So there's this mostly queer chick there who very plainly does not like me no how anyway, and I ask where's mens undershorts? In a partly onery attitude guides me to where they are at. It's times like that I ask the infamous question, of why is there not an alternative retailer in Evanston, beyond the population restrictions still having a second or third place to go at midnight for such things would be kuel. So figuring that bought my shorts, and picked up some moo to take home since I forgot earlier in the day, what with the going's on with Miss Hazzard County and all. The lack of dairy inside the Rode House here, was the main reason I woke up , put on my threads and ventured out into the cold in the first place. I simply need my milk. 
Earlier in the afternoon/evening these folks that reside over yonder here who I've asked to stop by multiple times as the wife of the couple would be a good on air person here on HazzardAyre Radio. When I mentioned that I still have the old silver Subaru he wanted to know what'd it take for me to let loose of it? I said get Smith's to get my Dewshine back on the shelves. In reality I ain't selling the car. Plans are to gut it, and build it into a hobby stock stock car. But I explained to my neighbor that I had been up for 24 plus hours, needed sleep, and was ready to call it an early day. Just as I was just exiting the conscience world, he comes bombing up my stairs which rattles the stair arm, which vibrates against the wall outside and thumps against the wall inside by my bed. You'd think the powers that be would fasten all that together more solid so that vibration would no longer hammer against my inner wall of my bedroom. Oh well, only excuse is they're Yankees. 
Is it just the low wages at Walmart and Smith's amongst others ? Or is it something else that makes retail employees, stupid or ignorant?
Had a great day getting together with our main candidate for Miss Hazzard County, 2017/18. Alesha is one of the classiest ladies for the task that I have met in a very long time. She's extremely pretty, very intelligent, and I wonder why she chose us, but I think we're blessed to having her on board. 
Took the night off of going on radio, needed sleep.
