Alignment Off After New Tires Installed

[ShirtaDay.com]

So I got some new tires put on today (35x12.50 Hankook's) to replace the Contis that were on the truck. After I got my truck back, I noticed the alignment was off. I now have to have the steering wheel turned about 30 degrees to the left to go straight. I would have turned right back around to the shop but I was the last one out - they literally left as I did. Is it possible that they messed something up? And if so, what? I mean, the truck drove just fine on the way there..... Not very happy at the moment...

If they just installed tires then i would say they messed something up there should have been no reason to touch the front end parts for just tires unless they jacked up on drag link or something!!
