A person replaced a 3 seat sofa and took the old one down to the building's Chatzer and willingly Hefkered it. He advertised it online to come and take it for free, mentioning it is in the Chatzer.
A guy called and said he's coming to take it. After an hour another guy called and asked if the sofa is still available. Turned out the first guy left a stick-it on the sofa with his name and ID number. It also appears that the sofa wasn't moved around.
Does the note points at his ownership, or can the second guy come and (rightfully) grab it?
