They don't wait long enough to have their pan heat up before they add their butter or oil.

That’s the real problem there. The oil should smoke a little when you add it, that means the pan is hot enough. You can check by flicking some water in the pan; if the water drops bead up and skate around the pan like they’re on ice (Leidenfrost effect), it’s ready. If it immediately fizzles and evaporates it’s not hot enough.
