For most people, "seeing inefficient code" is basically hallucinating. There's real truth to the mantra about premature optimization. I've seen people so many times worry about the performance of something, thinking that some code looks slow, when in actual reality it's a complete nonissue. Software development is all about compromises, just like any kind of real world engineering. Building a stage for a weekend festival is different from building a bridge over a river. We're always on a budget, so if I can work much faster and safer and lose some marginal efficiency, I'll do it—unless marginal efficiency is what I'm competing on, which it usually isn't.
