Is it necessary to do anything about a piece of cloth found on a customer shuttle bus that no one has asked about?

This piece of cloth is subject to the ruling of a lost item (Luqatah):

- If it is something that people of average concern would seek, then the worker must announce it for a year. If its owner does not appear, he takes possession of it. He must return it if its owner comes and it is still with him, or return its equivalent or its value. - If it is something that people of average concern would not seek, the worker takes possession of it immediately upon picking it up, and is not required to announce it.
