All you have to remember is if you know you are right or wrong, if you challenge mms and you are abusive then you have dropped yourself in it, if you are polite but still say it then they cant sack you,. What I basically say is - there is a line, you know deep down when you have crossed it and visa versa, if you feel you are right and in your rights then you are right, otherwise you wouldnt have thought it, if you know you are undefendable then accept it, you messed up.
Its on like Donkey Kong beeeaaattttcccchhhh!
