When I expect that the plane is going to need more than just an A-check for the preflight, I tend to make sure I arrive at the club half an hour to an hour before my passengers arrive. And when that's impossible, for instance because they're driving there with me, I either let them help me, or leave them indoors, whatever is appropriate to their expectations, expertise and ability.
Despite that, after a freezing night it's never a good idea to be the first to fly an aircraft that's spent the night outside. Always book an aircraft that's been hangared overnight, or make sure you're second.
