Yet another ridiculous complaint. I've deplaned onto the tarmac in quite a few airports, often from a seat in F or C, and never thought to complain about the weather. There are a lot of airports around the world that rely on ferrying buses rather than jetways, even to handle large planeloads. Somehow, people survive. Often times I'm even glad to promptly get a breath of fresh air (or semi-fresh, given the jet exhaust) since it's so scarce in a long voyage.
In short, geez.
