Whether they're winter wheels or not, he really shouldn't let jobs like that out of his sight in my opinion. I've not used him before, but I doubt I'd be inclined to in the future. However, as you know, there are other places who are little better or possibly worse. I'm more inclined to just live with the kerb damage that mysteriously appears on my wheels than run the gauntlet of refurb lottery.
Never mind, I'm sure he'll take them back and do them again properly.
