This sort of reminds me of the customers that used to come into Best Buy when I worked there with their recently purchased DVDs. They would show me the disc and point out a nearly microscopic imperfection.
Me: "Does the movie still play?"
Customer: "Yes."
Me: "Well then what is the problem?"
Customer: "I paid money for this there shouldn't be something wrong with it!!!"
Me: "Well you paid for the movie and you told me that it played fine."
Customer: "I want this replaced!"
Me *thinking* -- Ok you paid for the movie and you got your movie, you didn't pay for a flawless mirrored surface that would be up to spec for use in the hubble telescope.
Then I would just replace it since I knew if I said no they would talk to a manager and the managers ALWAYS cave in to complaints.
Those were the days..
