If you are a server at a restaurant and an obese person orders the most fattening thing on the menu, or if you are a bartender and someone you know is an alcoholic orders a drink... could you serve them with a good conscience knowing that it is your job to do so?

Should adultery be punished? We have the full gammit of legality to work with, starting from taking their tax benefits away to a stone on the wrist. It just seems like one of the more serious crimes that we turn the other cheek on. Of course, we can play the 'what is adultery' game, but for this argument's sake, the question is do you and how do you criminalize a physical sexual act with someone who is not your spouse?
