The Annals of Mathematics is a journal headquartered in Princeton. While I was a grad student, an Annals editor stopped another professor on the third floor hallway in Fine Hall. The editor showed his colleague a paper that had been submitted to the Annals, and asked for his opinion. The colleague immediately turned to the page with the author's university affiliation. He remarked on the lack of prestige of that (large public Midwestern) university and concluded that, due to where it came from, the paper should be rejected since it was very unlikely to meet the high standards of the journal. The editor thanked him for his help.
