Here's a thought. Electronic alignment equipment is sensitive enough that placing someone in the drivers seat is enough to throw the alignment off slightly, in some cars. Therefore, aligning the car with nobody in it results in an incorrect alignment when a driver is in the car.
A good alignment shop will put a person in the driver's seat to more realistically duplicate real-world load and conditions.
Another possibility is to rotate the tires. I have corrected a couple of 'pull' problems simply by switching the tires back to front.
