Reminded me of my tourist trip to Las Vegas. At some point we got on a bus to travel from one hotel to other. I asked the driver if that bus was the free one (meaning, if that was the bus in which I didn't have to pay). The driver replied a bit angry that the bus trip was not free, it was complimentary.
