Keeping things warm
We don’t know why someone would use a pressing iron on snow. Perhaps they’re attempting to warm up on a chilly winter day. But how will it work if she can’t plug it in anywhere? It reads as well like a significant risk.
It’s also conceivable that they’re bringing their iron to work so that everything is always neatly pressed. It’s still amusing that they had an iron on the snow for no apparent reason. We’re interested in where they think the iron will get its power.
