Target

So I was working today at target and this "guest" comes in the door and comes over to me and starts telling me about a tv that she wants... I show it too her and she tells me that she wants a different one? I explain to her again that the on I showed her is exactly what she wants. Then out of no where she starts calling me incompetent and that I have no idea what the hell i am talking about. My point is that people are stupid...
