I once worked for K Mart and while they were training me, they showed me all the things you have to check beause people try to take things free. like putting ladies panties inside a thurmos bottle, or hiding things in the folds of blankets that are in zippered plastic bags. I would never have thought of things like this. I guess I don't have a criminal mindset. glad I don't but a guy can get robbed blind if they don't check everything.
