Who is Bartender from Welcome to the Monkey House and what is their importance?

The bartender is similar to Sousa, who is drinking at his bar. When Heinz talks about babies and childbirth, the bartender sides with Sousa in laughing at him. The bartender has eight children and doesn't care to hear about the miracle of life. He gives up on Heinz completely when he learns that Heinz doesn't follow baseball.
