I suspect that might be stretching a point! The ship's people will contact the tour's people to see what's happenin'. When they hear that a guest is still spending money in the Diamond Store, they'll pull the gangway straight away!

you carry before you sail. And, get yourself a hard hat, as the lady's anger may manifest itself with "blunt object trauma!"
