I give my car a bit of stick occasionally, but I've never had premature wear like this before. The tyre shop put it down to the Euro's suspension geometry, and suggested they have a propensity to start chewing through rubber - particularly at the rear - if alignments aren't performed at least once every 10,000km or so.
Was your car lowered? If your car was stock, there is not much they can adjust in the rear in terms of alignment. So they were just trying to get you to come back more often.
