Bailee's particular lien: right to retain goods until due remuneration for labour or skilled services, subject to contract. A bailee who, in accordance with the bailment's purpose, renders services involving labour or skill in respect of the goods has, absent a contract to the contrary, a right to retain those goods until he receives due remuneration for the services rendered; this lien is confined to goods subject to such services and yields to any express contractual agreement modifying retention or payment terms.
