It is baffling. She simply used the issue of handicapped parking as an excuse to harass a stranger -- in front of a child, no less. Had she really cared about freeing up that space, she would have just helped you to get out of there quickly by holding doors, etc. She made it look like she had the moral high ground, but in reality, she was just an abusive person. I'm sorry it happened to you, but don't take it to heart.
