Fast Fries (2F) requires that its employees wear uniforms and protective clothing while on the job. 2F provides a locker room for the employees to leave their street clothes and personal items while working. A sign on the back of the locker room door states, "Fast Fries is not responsible for the loss of any property in the locker room." Grant, a 2F employee, changes his clothes in the locker room before starting work and leaves his wallet and watch in a pocket of his jacket hanging in his locker. When he returns after his shift, the wallet and watch are gone. Does Grant's leaving personal items in the locker room constitute a bailment? If so, what type of bailment? If not, what legal relationship is it? Does 2F's sign exculpate the company for Grant's loss? Why or why not?
