As my friend noted, literally all he needed was a sign saying PAY TOWING FEE HERE with an arrow.
This is the IMPOUND LOT, which is to say, the place where people's cars get towed, which means a lot of the people trying to get there DON'T HAVE A CAR TO USE TO GET THERE.
People arrive already in a bad mood. Making them play "guess which mystery building contains the office you're looking for!" is not going to improve anyone's disposition.
