This is a story I heard from a friend of mine who is close to the Steelers organization.
Troy Polamalu was out at a restaurant eating dinner. He sat down and ate his meal. During that time nobody came up to talk to him, ask for an autograph, or anything like that.
After he was finished eating dinner, he stood up to tell everybody in the restaurant that because everybody was peaceful towards him, he was taking the bill for the entire restaurant.
Whether or not the story is true, Troy Polamalu is one of nicest, most feared players in the NFL.
