Habit 1: Be ReactiveReact, react, react, and then overreact.
If you want to be a completely useless and ineffective bar owner or manager, you need to react to past trends and overreact to customer and staff feedback. Javelin Joe at Summers is a shining exemplar of reaction and overreaction. He reacted well when he signed a non-exclusive contract to show the Olympics at Summers and he overreacted when he ordered ordered a million metres of blue electrical tape.
To make the most of your ineffectiveness, and completely bamboozle patrons and workers and confuse them beyond reasonable doubt, you must not only react, but overreact. Take what one customer says one time about one thing the one time they come in the establishment and make that a policy. Then change the policy when another customer comes in one other time and says something different. Remember not to tell regular customers or employees, because you want them to react too. It doesn't matter if the change in policy is four hours or twenty-four hours, you can't gauge people's reactions unless it a complete surprise.
