he's suing to PUNISH THE COMPANY.

The problem arises when someone starts "punishing" a company for stupid shit.
Your water fountain doesn't have pressure high enough for a proper drink.
LAWSUITI tripped over my own shoelaces while walking down your hallway.
LAWSUITYour parking garage is too big, and I couldn't find my car for ten minutes.
LAWSUITYour vending machine sells roasted peanuts, and I'm allergic to peanuts.
LAWSUITThis kind of frivolous lawsuit is the reason why the cup you buy coffee in says "DANGER HOT." Of course it's hot, you walking ass sculpture! It's coffee! It's the reason those little packets of oxygen absorber stuff you find in the jerky or other merchandise says "DO NOT EAT." Why the hell would anyone WANT to in the first place!? This makes it seem like people have no common sense, which isn't true. People are just greedy.
A co-worker of mine had back problems. She was scheduled to undergo surgery sometime, but she couldn't pay for it. One day, she dropped a pencil, and strained her back picking it up. Rather than going through workers comp, she sued the company for as much as she could, which equaled out to about 40k. She got her surgery, in addition to a new truck. Today, she still gloats about her victory.
This elevator incident seems to be a proper lawsuit though. They should install emergency phones in those things.
