Violence at work

I arrived at a branch tonight to do extra hours exactly 3 seconds after someone was stabbed in the face with a broken beer bottle.
Yes that is correct.
Someone broke a bottle and then stabbed someone they did not like in the face with it.
Then they all ran.
For those of you who engage in this type of behaviour in libraries please be advised:
A) We library staff members don't like seeing violence at work.
B) All libraries have security cameras - you are being recorded.
C) Why the fuck can you not stab your friends/enemies in a dark alley like a normal thug?
D) Why on earth do you come to the library to get drunk and then fight? The environment is not really condusive and we have security guards for a reason.
E) We have security guards.
F) You will get your library privledges revoked permanantly unless you go to a hearing to have them reinstated. And well chances are that it won't happen. (I am assuming that you are at the library fighting to cover up the fact that you really enjoy reading but have to cut your friends/enemies to prove how manly you are)
