That is so petty. Just because your wife wears her jacket to work(not at work...mind ya) and some beotch has to give her shi*. I wouldn't push the issue just for the fact that now a days yes they will fire you for anything. At Trinity grill by my house a server got fired for her "laugh" . Yup you heard it the boss didn't like her laugh and told her if she laughed again she would be fired. It was on the news and with that being said let your wife's boss(lil miss Hitler) think she has won this battle. I can't wait to move to Colorado where they can't fire you for stupid crap!
