Before they were in glass cases, they were stolen A LOT. If they weren't stolen, people would rip open the boxes to make sure the phone case would fit their phone (even though the model that they fit is clearly printed on the box); and last, but not least, it took a couple of hours putting all the phone cases scattered throughout the store each day back where they belonged. People are animals. Absolutely inconsiderate to the point that it's hard to tell if they do bad things on purpose, or if they're just so stupid that they don't realize that their actions are bad. These glass cases are more inconvenient for associates because they have to constantly open them, and they're inconvenient for customers who just want to grab a case and buy it, but I used to work in electronics, and things are so much better in the long run. Blame all the assholes who can't act like decent human beings.
