Frank the Car

AKA The Undertaker collects rents for me in the East End of Glasgow. I hasten to add he is called The Undertaker because he is somewhat eccentric, wearing a top hat and driving an old hearse. He is known as Frank the Car because he fixes cars that are not working.
Anyway, Frank collects the rents because he is a tenant of mine within a small industrial complex, and he collects everyone's rents and then delivers them to me. He gets paid a small amount for doing this.
The reason he does it, however, is not for monetary gain. It is because Frank LOVES talking to people. He doesn't sleep well, and frequently toddles into one or other of the Glasgow police stations for a chat at 3 or 4 in the morning. I often get a text from him at midnight, telling me some extraordinary tale. I am reminded of Terry Pratchett's Ankh Morpork city with denizens of the night lurking in the shadows.
What I hadn't realized was that Frank is actually following in the traditions of some Indian beggar caste that bothers people for money. There was an article recently in Private Eye about how the Indian tax people had hired the beggars to collect tax from recalcitrant payers. They were so succesful that they only needed to do it for about a week, and over 90% of the outstanding taxes were ingathered - with the rest promised within a further week.
Frank clearly works on the same principle. He starts talking to the tenants about 72 hours before the rents are due, and doesn't stop until they give him the money. Frank always turns up on our doorstep at least 24 hours before the cash is due - with the money.
So spare a thought for those unfortunates who have to cough up - the pen may be mightier than the sword, but the tongue is mightier than your willpower. As one tenant put it to me " He does my head in"
