Here is the other thing to consider, liability for what those sh!t faced people do when they leave your establishment. Here in Ontario, if an establishment over serves someone, or even serves one drink to someone who came on that way, the owner of the establishment is liable, and can be charged and the case of a drunk driving fatality that owner can do time. Way too much responsibility for this guy.What clinched it for me was serving beer on a very busy night, the customers were friendly enough, but pretty $h1t faced. It got tiring very quickly. I knew then I would never do it.
