She is not special and has no right to disobey posted rules for the Metro. I am not special either, which means I follow the posted rules. What about this is so difficult to process?
If she hadn't been defiant this whole thing would have been avoided. Finish your food before you enter the Metro.
You have to prove to me (and the judge) that she disobeyed the rules.
Looks to me like she did what was asked of her, and no more.
