Toilet rooms - enclosed. Except where a toilet room is located outside a food service operation or retail food establishment and does not open directly into the food preparation area of a food service operation or retail food establishment, such as a toilet room that is provided by the management of a shopping mall or a toilet room designed so as not to need a door that opens into the sales area of a retail food establishment, a toilet room located on the premises is to be completely enclosed and provided with a tight-fitting and self-closing door.
