I mean, I guess people hold up liquor & convenience stores for less money and a lot more risk. It is unlikely a Gamestop would have an armed employee, and like the article said most of them are down to 1 employee per store at any time. So for a $500 console, it's probably a pretty safe bet for a thief. At a liquor store or convenience store they risk getting their heads blown off for whatever is in the register.
I hated working nights by myself when I worked retail. I never got a gun shoved in my face, but there were plenty of times when 2 or 3 scary people would come in the store (obviously a team) and steal stuff and there was not much I could do about it. That was also before everyplace had surveillance though. Of the 4 stores I worked at, only one had a camera that worked and was recorded. Another had a camera that was disconnected but "rigged" for the red light to be on. The others had nada unless we went out of our way to have a camcorder running.
I called the cops several times but it was always after the fact, and they were like "what do you want us to do about it?" . Not like I could actively call 911 WHILE they were in the store harassing me, and most times had no video proof.
