Do they have a lost and found

There is a lost amd found at the port Authority. You may not find your belongings, but it might be fascinating to see whats actually there. Lol😄

Yes

it has alot of homeless people around so they usually keep lost stuff

Nope. I had lost something and called them but they said no one found it in the bus so someone might have took it. But if you call them and tell what bus you took and what did you lost, they will contact driver to see if someone returned something.
