Hold on though before you judge. In my defense, some items simply scream "steal me." Take certain protein bars for instance. They know they're damn pricey, plus they strut their stuff knowing how damn good they taste. They're all, "I taste like a chocolate bar but I'm all good for you and shit....oh so good for you. Now steal me dammit and maybe buy some porn while you're at it." So, I tend to comply in those situations.
Furthermore, certain cashiers send direct signals to the consumers indicating that now is the time for some good, old-fashioned shoplifting. For example, I went to my local pharmacy yesterday to buy some syringes. Well, I asked for 80 but the guy said he only had 68. Suspicious? Hidden meaning? I think so. As if that wasn't enough, he went and totally undercharged me by like half the price for those 68 pins. At that point I knew he was trying to convey a message to me. He was obviously trying to say, "Hey buddy. Steal some of those vitamins down there. They're good for you so you won't be hurting anyone by just taking them. Also, I like your pants." I took the vitamins and thanked him for complimenting my wardrobe. I thought it was a great touch when he pretended like he didn't know what I was talking about.
Anyways, shoplifting is a victimless crime. Only the store-owner loses out and thus everyone who counts is left happy and content. I think I'm gonna go steal me a puppy.
