Very well done by her. I didn't think the other woman was "flipping out" but the worker was definitely in a tough spot,. The woman being surprised at Pete's sexuality, irrespective of her opinion on the topic, definitely shows that she is pretty damned uninformed and probably should not vote for anyone.
Although not filmed, she took back her card and turned it in for Biden then said "wait a minute, are you telling me this guy sniffs people's hair"?
