What is ironic about this passage?

"God bless them! From that first day, I drank tea free, coffee too. I ate the best food in the restaurants free, and in addition, they gave me pocket money. It kills me to think that while these poor people were suffering all those years from the lack of a loony, I was putting numbers on documents, kowtowing when I entered the director's office, and wasting all that time for a mere thousand lira a month. If I'd known, wouldn't I have come to this town long before? "The people are so happy at finding a loony that they don't even ask who or what he is or even where he comes from. Now when I enter the mayor's office, I don't say selam or hello and don't even bother to knock. I walk right in, lean against the mayor's arm then settle myself into an easy chair. After thrusting an expensive cigarette into my hand, he lights it with his own lighter and orders me a coffee. While I drink my coffee, he asks, 'You have any problems or anything, Hilmi?'
