Another "hint" that might help in the future, if not now....most chain stores put the guy with the LEAST experience on the alignment rack. They want them to gain a good familiarity with the different types of setups and the relationship of the parts to each other.
Therefore, you also run the risk of getting the guy who'll use a 12 point socket to try to break a stubborn rusty cambolt, too.
I use shops that specialize in suspension and alignment, actually the guy I use is a one-man shop, and he's been doing it for thirty five years and has the best equipment...oddly, he's also the cheapest around.
Must be from not having to deal with comebacks and lawsuits for doing stupid things....
