Should bartenders be held responsible for the behavior of their patrons?

          My opinion is that they should not be held responsible for a person's behavior. The person acting in a bad or good behavior is responsible for themselves. They are grown ups why should someone else be responsible for them. People should know their alcohol limits they can take, so they don't cause a ruckus or destroy anything. The only two things a bartender should be responsible is to make people their delicious drinks and to check everyone's I.D. They need to check I.D.’s so that there are no minor drinking any alcohol in their establishment because that could ruin the business. Also make the drinks, if no drinks people don't come so no sales to keep up the business.
