Early in my military career as an Army officer I was assigned to a unit where the Executive Officer, my boss, clearly hated going home to his family at night, and wanted the officers reporting to him to join him nightly at the officer's club for hours of boozing. Most of my contemporaries were single guys and more than glad to enjoy the free booze (the boss paid for the drinks). I usually would stay for a drink, or two at the most, and then leave to join my wife for dinner and the evening. Without a doubt this had a negative impact upon my performance evaluation. Fortunately for me the unit's commander, who also had a role in my evaluation, thought highly of me and my performance on the job, and that tempered the XO's trying to punish me for not willingly joining in to his lifestyle. Excessive alcoholism seems to be not uncommon in many organizations including parts of the military.
