Twenty-two food sellers today started dismantling their food shops which had encroached on the Hua Hin beaches for the past several years as provincial and municipal authorities carried on with their cleanup campaign to reclaim the beaches.The food sellers were given an ultimatum to tear down the illegally-built shacks which served as restaurants and to remove their properties out of the beach by today otherwise the officials would dismantle the structures themselves and the sellers themselves might lose the right to be given a new location to carry on with their business.
