The customers are the worst part.
"Ohh and be gentle please we want a light cruise past the harbors, none of that sideways stuff."
"......... next door is doing motor cruises, maybe that's more suited for you."
"No, we are sailor people!"
Or people who don't want to wear a sailing suit because it messes with their swag, until they get wet.
But worst are the know it all's who proclaim that everything you do is wrong.
