Haha, you are an intriuging character James. Sorry to hear about your troubles at Wal-Mart.
I recently had some troubles at my local Wal-Mart in Mebane, NC, not with OC'ing though.
To make a long story SHORT:
Basically the night manager refused to sell me handgun ammo at around 11:30pm. At first he told me it was because the Sporting Goods guy had left at 10pm. I told him that was fine, and that he could just walk over to the sporting goods section with me and use his keys and then walk me and the ammo back up to the open registers. THEN his story changed to "Wal-Mart has a policy of no ammo sales from 10pm to 7am" (the hours that the Sporting Goods dept is closed). I told him that this was incorrect, and he remained very persistent with his new stance. (Oh btw a friend of mine had been turned down by Kevin just a couple of weeks earlier, but he just "gave up" and never questioned it)
So I left, without any ammo. (Oh btw I was OC'ing this entire time, as I ALWAYS do every time I go into Wal-Mart.)
The next day, I called Corporate Wal-Mart in Bentonville, Arkansas. I explained to the nice lady what happened and she confirmed that there is NO POLICY against ammo sales at any time of day or night or holiday or whenever, and admitted that during "afterhours" a manager or some other supervisor with keys would have to take a moment to go out of their way to open up the ammo and walk it back up to the register. She said they would be contacting the store manager (the top dawg), Matt Adams. I decided to go ahead and do the same thing, just to give him my version. Mr. Adams was very polite and he apologized for having a mistrained night staff, and vowed to make certain this was corrected.
Two nights later, I stopped at Wal-Mart around the same time after work (11:30-ish), and asked the greeter to radio Kevin (the night manager) because I needed him to get me some 9mm ammo. She had witnessed the entire "scene" two nights earlier when he denied me for ammo. A couple of minutes later, Kevin showed up and I once again repeated that I was there to get a box of ammo (which btw I did NOT actually need anymore because I had ended up going to my local gun shop the day before and buying some). He walked me to the sporting goods section and back and I tried my best not to crack a big grin the entire time we were walking. We never once discussed Wal-Mart's "new" store policy during that time.
The little greeter lady at the front had a look of shock on her face as I walked out of the store with my 50 round box of ammo and 9mm compact bulging off of my hip.
