Pam Horton is the bartender of the Outpost Tavern in Houston. She is the former girlfriend of Ellen Waverly.
History
At Outpost, Gordo storms in angry because Ed did not say anything to him about landing Apollo 10, since it was not only his decision and he had not ask him what he had thought. Ed told Gordo everything was a joke to him, but he owned what he did and told him he resigned from NASA and would go back to the navy. Gordo could not believe it and asked Pam for two whiskeys.
