Is anyone able to help me with the concept of determining if a bailment was created?

After work last night Mary Smith and her friends went to "happy hour" at a swank local restaurant. Prior to sitting with her friends around the dinner table, Mary gave her Calvin Klimbe Fedora along with a $1 tip to the attendant in the restaurant's coat check room. The attendant then gave Mary a claim receipt for her hat. After "happy hour" was over , Mary returned to the coat check room and noticed that the room was dark and that there was no sign of the attendant. Mary showed her claim receipt to the restaurant manager and asked him to assist in finding her Fedora, but after searching for an hour, the Fedora could not be found.

Was a bailment created? What are Mary's damages, if any? Explain your answers.
