Friday morning shortly after 9am I called the Detroit Transportation Corporation. I spoke with a woman and told her I wanted to speak to a supervisor about the incident [[FYI - I spoke in a very calm, polite, and non-confrontational manner). She said a supervisor wasn't in but inquired into why I was calling. I told her the story and she seemed concerned and as if she felt it was wrong. She said a supervisor would call me, that never happened during the course of the day. Perhaps I get a call next week.
