Travelling Rug Salesman?

My elderly parents were doorstepped by a rug salesman today. Slim. 5'10. Dark hair, dark tash. Said his name was Manolo or Manuel. He has called before so they were happy to chat, initially, but he became quite persistent and wouldn't take no for an answer until I intervened, thanked him, and closed the door. In a dusty car (didn't get the make) with his wife in the passenger seat. Might be the nicest man in the world and just trying to make a living, but I'd appreciate any feedback anyone might have.

Thanks in advance.
