I might get flamed for this comment, but frankly I do not see the big deal here. Why should she get in trouble for something this minor. F/As are not waiters/waitresses. She made a simple mistake - probably not something that happens frequently (otherwise it would be all over this board). If you asked and she still refused then I could see an issue, but we are all human and sometimes things do slip our mind (besides, dtw-phl is like 80 minutes at most). Why not just chalk this up to a one time occurrance and hope it doesnt happen again?
