I think that would be true if I were to pay them by the hour. Fortunately, I'm not (at least not in the case of the remodel I'm going through now), but it means it's on me to make sure everything is the way it should be. I guess it's still a way for them to gamble - if I find a problem, they'll come back and fix it, but if I don't, that's some saved time for them. I'm ok to play this game, but it's not making me believe in "pros will do it right".
