The only ship i was on with a free drink, was, i think an Ellerman Papayani boat, but i cannot swear to that. It was once a week on a weekend and was a tot of cask rum, in those days i could not stand spirits, not so now of course, but i was always persuaded to draw my ration, and had willing takers of it. I know on tankers when cleaning tanks there was a tot, but i never served on tankers. kt
