You hire them up front, wages paid before they sail. Every one of them has something wrong with them: afraid of lightning, useless in fog, keeps their hands busy so they stay off other people. You will not find out which until the boat comes back.

They do not haggle. They walk in, take a fish off your stall, and run.

There is a bat behind the counter for the last two.
