I once followed a CL ad for a free Weber to a curbside like that. It was also a lonely black 18 OTS, a little older. Came with a Weber chimney and lighter fluid which yes I did use. Cleaned and flipped for an easy $10 to a college kid just starting out grilling and we chatted briefly about technique to get him going.
That was the best part, the $10 revenue was of course nothing.
