Bars and restaurants that serve liquor run the risk of patrons drinking excessively, thus becoming dangerous to others. Fights can break out when two drinkers disagree on something that involves their egos. Patrons who aren't even associated with the drunks can get injured in the process. A bouncer can get hurt trying to break the fight up. Lawsuits can occur for all these incidents, including when a bouncer injures people.There are various other ways besides drunken behavior that your restaurant or bar can get sued. If a customer trips and falls in your restaurant, they may sue your establishment for unsafe conditions. Another way to get sued is if your food or drinks cause illness. Serving liquor to minors is also another way your business can wind up in legal trouble.
