I remember back in the early 80s when I worked at the ferry dock at the west, because it was tidal it used to take 45mins for the ship to be pumped up at low water, enough for any cars or passengers to disembark.
A disgruntled American and his wife came off and wanted to know why things took so long.
After explaining the way things work he said.
"Why the hell could'nt you have done that before the ship arrived "
