Wow. Major personality disorder.

That was an interesting way for someone to get service. Buy something then go to web sites and slander the product, its makers and distributor. Go to the site associated with the designer and threaten to continue your slander at various web sites every twelve hours until all your demands are met. Blackmail much. Along the way gratuitously insult everyone and generally work hard at coming across like the world's largest inflamed hemorrhoid.

Can you imagine what being in a survival situation with this guy would be like? Perhaps trapped with a climbing group on the side of a mountain. Forced to ration food and water and packed like sardines into tents.

Things don't go exactly his way and he bypasses normal communication and all expectations of civility and jumps straight into leveraging his ability to make life miserable for everyone around him through insult, slander, spreading accusations and generally raising a stink.

In just about every likely disaster scenario getting along with people will be a vital skill. People under stress are unlikely to have much tolerance for such agitation, lack of patience, and verbal abuse.

On the other side it does open up an interesting question: How do you deal with difficult personalities? Do you give in and let him have what he wants? What if he wants more than his fair share? Do you 'help him off the mountain' the hard way? Or do you hog tie and gag him for his own protection before someone gives him impromptu 'Flying lessons'?
