Also - in my state and presumably most others, it is against the law to bring a weapon into an establishment serving alcohol. A good idea to forego the sgian, or at least tuck it somewhere outta sight.
If you're worried about things getting rowdy, go to your local bank and get a roll of nickels(Make sure it's one of the plastic rolls, not the paper)... instant fist pack, no concealed weapon. Or just wear steel toed boots like I do.
