Pyrates Royale Cruise: 2009:(sorry, it looks like the ":" dispensing machine is stuck in the on position.

The band took a cruise with several of our fans to Bermuda. We had a great time. A fair number of our fellow non-band-fan passengers were unfortunately obnoxious self absorbed Ugly American tourists.
One of the features of these cruises is that there is ALWAYS food available. No one will ever starve on a cruise ship.
Another feature is the self-dispensing hand sanitizer ball. Since our co-passengers can't be trusted with normal hygiene, these little ball-shaped dispensers on poles were everywhere on board. Their photocells were always at the ready, waiting for an initiating hand pass.
I don't normally do breakfast, got up early one morning to see what all the fuss was about.
I joined the line behind a fellow who had obviously been to many breakfast buffets. His plate was piled high with eggs, biscuits and gravy, sausages; but this wasn't enough for him. The one thing he needed to make his world perfect was French Toast. Unfortunately one of the hot plate burners the chef was using had gone T.U., and he was doing everybody's orders as fast as he could on one.
From the way this guy was complaining you would have thought that the extra wait of a few minutes was a war-crime. "You should get another grill up here right away. Why aren't there two cooks here. Don't you people know how to do anything right???", etc. etc.
As he whined on, the roll of the ship repeatedly eased his plate under the sensor of the hand-cleaner ball that he was leaning on..."Why don't you (whirrr) folks get more staff (whirrr) up here to (whirrr) fix this problem (whirrr). It's simply tolerable that (whirr) this kind of shoddy (whirrr) service is allowed (whirr)." The funniest part about this is that the guy was doing it himself. He got his food and waddled off to his table.
I hope he enjoyed the French Toast. I know that those biscuits and gravy were probably disappointing.
