I told them that my computer was in my back pack and somehow got dented at the airport, maybe dropped the bag too hard on the ground or something. I told him that I feel horrible for denting my month old MBP. The genius said he felt my pain and he will give me a new MBP because its not worth fixing. I was shocked and thanked him a million times.
