This American fixation with the word "free" always makes me chuckle. Aa when a bus driver in Las Vegas got angry when I asked them if thag was the "free" bus, and he angrily replied "it's not free, its complimentary " .
Maybe you saw it on a previous story where I shared it as well? If you look through my comments you'll find it. Albeit a bit more expanded I think. Sorry if this bothered you.
