tax agent
I am a tax agent in the kingdom.  The king has appointed me to collect taxes on his behalf.  I collect all the money because that is right.  I don't have the patients for the liars who try to cheat the king.
I have come to collect taxes on behalf of the king. Oh yes of course, sir! Excellent, it appears that you may owe a good bit according to my records. Here is my log for this month's sales. I hope you find it in line with your records. It appears to be in line, which is good for you because I despise liars who try and cheat the king. Oh I would never dream of it! I am here to make an honest living, and sell quality supplies to the vessels that dock here. That is good to know, you do have the full payment of 50 silver coins yes? Why, yes I believe so. Please browse through my wares while I retrieve it from the back. -looks over the goods- My forgiveness Sir Agent, but I appear to be short on coinage. Could I offer you this silver handled knife perhaps to make up the difference? How short are we speaking? I have 40 of the 50 you have come to collect. The silver in this knife is surely worth 20.
