Mark was a local Las Vegas bartender who refused service to an intoxicated guest.  The guest came behind the bar and assaulted Mark, who had a pre-existing heart condition.  Another guest intervened before anyone was injured, but Mark succumbed to a heart attack immediately after the incident.  Mark was the smartest of all of us, loved for his witty banter. We hope to help his husband with Mark's final expenses and other financial needs due to his loss.
