If the licensee "manages the retail floor space," they need a Class 12 permit.
A "manager" would be someone who is involved in the day-to-day operation of the business, is normally available at the premises a portion of most workdays, is involved in hiring/firing people, ordering liquor, banking, and the sale and service of alcohol by supervising employees who sell/serve alcohol or may do so his/her self. Most liquor licensees will have to obtain a Class 12 permit.
If the licensee does not manage the business, i.e., does not spend time there, just collects money and hires a manager to run the business for them, then the licensee will not need a Class 12 permit; the manager will.
