"You can't buy three", part II

A guy had bought five iPad to help friends around the world. Article.
“I’m sorry sir, but you have reached your lifetime limit of iPad purchases and will not be allowed to buy any more.”

"lifetime"? However you look at that, that's weird.

A friend of mine in a culturally unacceptable in a store in his town, and was banned. Two or three years later he went back in, and and was summarily and physically thrown out. He also got confirmed that the ban was literally "forever".
I think it's crazy. Unless we're dealing with a psychopath here, I would say that if you ban him for a year, he will get the idea and will not misbehave again. And if he does, give him two years. And five next time. "Forever" is nuts.
People always go to extremes way too fast.
