Almost without exception. There is no way of knowing without careful study which burner will turn on when you turn a knob. (generally you know the side, but not front/back) Every time I move I need to figure out a different stove, and so I'm often turning on the wrong burner because I have the wrong habit. Most people think "opps, I'm stupid again" when that happens, but I have enough UX background to know that the real problem is the UX is terrible.
