If you had an in-spec alignment when you left the shop but it has since gone south, you're dealing with either an incompenent tech who forgot to tighten one or more fasteners after making adjustments, or you have one or more badly worn suspension components. Not to mention that if you have suspension components which are worn to the point where the car can't be aligned properly, any shop worth its salt won't touch the car until those components have been R&R'd.
You say that the front wheels look like they're out of whack, but how does the car handle? Did it handle nicely when you left the shop immediately after the alignment, but has slowly degraded over time up to this point? Has the handling changed suddenly over the last couple of drives, or what?
Unless you're dealing with an extreme case of misalignment, the human eye generally can't tell that the alignment is out of spec just by looking at the car. Especially if you're comparing wheel orientation to body panels.
