Expect
the unexpected. It's a common enough saying, but one I think that's especially
true in this business.
Take for example an incident that occurred not too long ago at a high-profile sports bar in Florida. A young man seated at the bar was beginning to show signs of impairment, so one of the two bartenders on duty refused the man further service. He became suddenly enraged, withdrew a knife from his pocket; and with all deliberate force, impaled his own hand to the bar top.
