To throw some food for thought on to the discussion, I find it important to note, that in most retail stores, you are in charge of your department/cash register, what ever it is. I don't know how stores handle shoplifters that are customers, but I do know that if the manager suspects that it is another employee, and can't pin it down on any one person, then the person working that department is responsible for the loss. Eventually, that manager will start taking the loss out on Will's paycheck.
Shit rolls down hill, every thing has to be accounted for with the inventory. When shit starts turning up missing, who ever is above the manager starts getting on his case, then he has to bitch at the people below him for it. Most of the time when a person gets away with stealing one game, they will do it again.
