There is a gas station a few hundred meters West of the Temple of Heaven's North gate. It is very popular with motorcyclists because it has never asked for the blue book or DLs, and the pump people are always pleasant and smiling. You'd also see a lot of the three-wheeled box-thingies filling up there. It was usually quite a busy station.

Went by there yesterday and, noticing it was almost empty, I zipped in for a fill-up. They had a table set up next to the pumps, with a big book (like an accounting ledger) being managed by a grumpy old guy (maybe the owner?). Everyone's DL and blue book detail was jotted down and photos taken. Became obvious why this place was not busy. And I also understood why the old guy was grumpy - I'd be p'd off too, if I was forced to have my business partake in this silly system.
