I've got into the habit of removing the cap whenever I extend the lens, and not putting it back without retracting the lens. That has reduced the incidence of blanks but there's still the odd one. A friend who watched me framing a shot with the cap on once remarked "Ah, what you see is what you would have got!" and that's kind of stuck in my head
