Take the car to a reputable tire and alignment shop. Observe when they put it on the rack from the back and make sure the car is actually straight. Alignments can go bad from the start if:

1) The guy doing the alignment is more worried if his girl is doing his roommate and not paying attention to his job.

2) Damn Dude, 4:55 on Friday. Get that thing done so we can slam some brews.

3) Friggin' George Bush and global cooling. My Mom in Buffalo has been out of power for like a week and sh**.

Jokin' holmes. We all got to have fun once in a while. Seriously though, a front end can be aligned, but not with the rest of the car.
