Radley. In 1971 detached from Odiham to the Bahamas. One night in down-town hotel before deploying to the out-islands. Next morning clean teeth,bend down and cup hand under cold tap to rinse,turn on tap and suck: aware of more than water in my mouth: spit out biggest cock roach I've ever seen. Equally unhappy it galloped to the plug hole and disappeared.Probable "Exit left laughing."
