I found a couple of other tips. My favorite is to loosen the screws clamping the stem to the steerer tube, rotate the handlebars 90 degrees, and tighten the screws. A thief won't bother to cut the lock unless he has a suitable wrench, and if he is carrying one, he might be too self-conscious to adjust your bars in front of a busy pizza place. If you use security screws, even a well-equipped thief probably won't have the right driver.
I had a hard time adjusting handlebars to be exactly parallel the axle. When I had it right, I put a piece of masking tape across the crack where the stem meets the steering head, then used a box cutter to slit the tape at the crack. Now if I undo the stem, I need only line up the tapes to get it back right.
With mechanical brakes, a quicker tip is to reach through the front spokes with a long Allen wrench to clamp the wheel by tightening the brake adjuster. On my bikes it's less than a quarter turn from properly adjusted to clamped. It won't stop a thief from cutting a lock, but then he'll find he can't ride or push the bike. I imagine he'll quit instead of troubleshooting the problem and buying a tool at the nearest open shop that sells long 5mm Allen wrenches.
