I usually just stop outside the building I'm delivering to, step onto the curb and take two steps towards the railing and lock my bike or go up onto the pavement via the dipped curb when approaching the building. I've already had two fines for riding on the pavement so I'm not too keen riding up onto them, as well as the aforementioned pinch flats on the rear tyre.
