on the Alaskan Cruise that ended on July 12th; personally witnessed 2 patrons that refused to sanitize hands before entering the Beach Blanket Buffett but still went through line; witnessed another patron who placed the serving tongs directly on her hands and then replaced the tongs to be used again; whole family contracted Norwalk; have reported all of this to the Cruise Line; Patrons should demand that ALL passengers sanitize prior to being allowed to go through the Buffett line
