Good question and i have always wondered that myself. Its always been my understanding that things move very slowly in jamaica and it taks a long time to get the proper license to sell alcohol so in he meantime while they are waiting they must display a sign saying they have applied or intend to apply so that they can sell alcohol. Not sure of the laws there regarding the sale of beer and alcohol and always wondered if the people who sold beer out of coolers on the beach or the beach road were breaking any laws
