I'M SO ANNOYED RIGHT NOW!!

So I go to ToysRus Woodmead to buy a pressie. As they offer free wrapping paper, there I am measuring and cutting to wrap it. One of the shop assistants is standing there starring at me, then tells me I'm wasting paper, that's too much paper I'm using? . So I ask her "do you want to help me"? and she goes NO you do it yourself!!!

Like what the hell!!?? You offer an added free service for your customers to wrap for themselves, then have the nerve to stand there and tell them you are watching them, like I'm gonna ***** the damn paper!!???
