DOWNTOWN LOS ANGELES — The City must have decided they're a bit hard up for cash. There's a guy here at the office right now who's going door-to-door in the building trying to make sure everyone's up on their City Business Tax registration. Most people have never even heard of the BTRC, but as treasurer of the neighborhood council I'm all too familiar with it. The City has no intention of paying money to people who aren't paying it, so we have to get BTRC numbers from businesses in the City limits that we go to pay. You definitely get a good share of "What number?" when you go and ask for it.
