An Australian postal worker snapped a picture of a package from a dad who was so full of rage, he needed to let the world (or at least the mail carriers) know. The UK-based father shipped a guitar to his son, who lives in Australia. I've never shipped a guitar across the globe. But I have shipped other things, and I know anything involving the post office can be a complete nightmare. So I am feeling this dad's rage.
