I worked dogwatch in a servo in Sydney I the mid 70's, two dudes walked up to the bowsers, no car, no container, asked for a pint of oil, I said what type, and one dude just picked up a pint bottle from forecourt shelf and started to drink it!....he gave some to his mate and they walked off?...dident pay, I did, I dident mind one bit, and I thought I was "out there" lol...
