Can Someone Explain (Short Rant)

Why is it that people loose common sense trying to load or launch. Why is okay to leave your boat tied to the courtesy dock with your wife/girlfriend entire party sitting in your boat looking bored while you grab your trailer to load while the 20 other boats would like just a small spot to drop off someone off to get our trailer?

Why is it that rest of the 20 waiting have to crowd the courtesy dock so even if we find a small spot to drop someone off you have about 5 feet between boats to navigate back out and wait?

And finally, why is it the guys with the 1,000 mile per hour boats that are so damn loud your can't hear for days have to rev their engines while idling right in front of you?

Okay - rant over - thanks for letting me vent.
