Heck, in this type of situation I probably would have felt it worthwhile to miss my flight and call a LEO myself.

When being threatened by the manager (i.e. the I'm-telling-on-you statement), I would have whipped out my cell phone, turned to the manager and said "That's a good idea. I need to ensure that my rights are protected and that I'm not violated any further", then dialed 9-1-1.

I wonder what her response would have been then...
