Herman is opening up a new restaurant, The Krusty Krab. Herman purchases equipment for his kitchen from Restaurant Supply, Inc. on credit, and signs a security agreement. Restaurant Supply wants to make sure that this loan is properly secured. Because Restaurant Supply cannot retain possession of the property, Restaurant Supply can: file a notice of loan with the office of the appropriate government official. post notices in the restaurant that Restaurant Supply has a lien on the equipment. file a financing statement with the office of the appropriate government official. do nothing; Restaurant Supply already has a security agreement signed by Herman
