2 sunsail credit card captains strolled down my dock and asked me about how to get their boat off the sand bar/rock they had got stuck on.
I said the tide was due in and they should float or take the line from their mainsail and, pull sideways while motoring. They opted to wait it out I inquired about their anchor and was the line out enough to float free only to be told they hadn't dropped the anchor as they were stuck and after asking about the rest of the crew discovered there was only them and no one aboard.
Not as bad as above but these people charter your boats in the fleets...
