I was at that store the other week and initially wondered why so much was locked up, but then I encountered the performance artists responsible and learned they have it down to a science. They pick fights with other customers, often involving allegations of racism (which I saw first-hand were completely untrue). And the security doesn't want to have anything to do with it, so they let the perpetrator leave the store unmolested. It was an interesting experience but I couldn't imagine working there or shopping there regularly!
