You guys just kill me!
You read one article (and not even a very thorough one) and all of a sudden you're an expert on the law, loss prevention, and Apple's policies, procedures, and purchasing policies!
Every single one of you who states as an absolute fact that Apple or the customer was right or wrong in this case is talking out of your butt. You weren't there, therefore you do not have enough information about what actually happened.
Also, if you don't like Easy Pay, then don't use it! The Apple store near me is always busy, and I appreciate being able to just scan something and hit the road. You probably have a better chance of getting mowed down by mall security on a Segue then you do getting "busted" after making a legitimate purchase with Easy Pay. Just because you may not fully understand how it works doesn't make it a bad idea.
Opinions are one thing, but really - you can't say for 100% certainty that the kid didn't break the law, or on the flip side that Apple didn't screw something up. That's why we have the courts, folks.
