The Tampa Bay Times website said she wasn't in the costume for Tuesdays game.
Guess that explains why when I went up to Thunderbug and said, thank you for putting those nasty Boston fans in their place, the mascot covered it's eyes and make the "shh" sign.
Florida is a right to work state, so there isn't much anyone can do. If she had been fired before, and this particular incident wasn't team approved as per the Tampa Bay Times website article, it's a pretty clear cut case.
Unfortunate for her because it was hilarious. I should start bringing silly string to games and putting it on Boston fans.
