Minnie Moore is a museum curator in an abusive relationship with a married man named Jim.
Seymour, working the parking lot, witnesses the commotion and enters into a physical altercation with Zelmo.
Jim is waiting inside with his son and ends the relationship, revealing that his wife has attempted suicide.
When Minnie fails to introduce Seymour to her wealthy friends on the way into the bar, he angrily drives away and strands her, just as Zelmo had done.
