Naked men and corporate conspiracies

I started orientation for work last week. It was so hideously boring, but I am quite happy to actually have real money I'm bringing in. My first test is on Wednesday, so I'm trying to do some final review for that, and then I start full time the following week. I'm kinda nervous to start, just cause there's so much to learn all at once, but I think I'll pick it up quickly.
I had to do orientation with a teenager and another young guy who will work out in the general store, and they made me feel very old. The teenager was tiny, didn't have a driver's license yet, didn't know what direct deposit was, and wasn't even sure if he had a bank account or not. The guy in his early twenties worked for Walmart previously, and he had injured his back there. They wouldn't let him do worker's comp, but they paid for some medical visits. After he was done getting treatment, his boss told him to change a sign over the cart storage area. The only way to get to the sign was to climb on the carts or move all of them and get a ladder. His boss told him to just climb on the carts, and so he did. Next day he got called in and was fired to breaking store policy. He explained that he was told to do so by his boss, who was visible in the video footage. She claimed she was telling him to get down, that she never said to do it in the first place. So he got fired. It was a good setup so the company couldn't get sued. Pretty slimy business, but not terribly surprising from that company.
On Thursday I was doing some computer learning stuff at work, and the men's bathroom was right across the hall from me. Apparently, a guy went in there and took off all his clothes and refused to put them back on. After an hour of security people failing to get him out, they had to call the cops. Somehow, they figured out who he was and called his son (I guess he was an older guy) who came and convinced him to get dressed and go home with him. Man, it sucks getting old. I don't want to get to a point where I get naked in public restrooms and have no idea where I am and need my kids to come get me.
