The damages he suffered was that he puked; and that's worth 50000 dollars? While they may have served him a very unappetizing sandwich, unless he suffered much more damage than upchucking, his request for fifty thousand dollars is just evidence of his opportunistic traits.
I can just see him describing to the jury the terrible impact this has had on his life, telling them of the mental anguish, and how he can't sleep, eat or work, since such a life altering event. Poor baby.
