In a way I can share your frustration, although that hasn't happened to me, YET.

My mail carrier wears an Isle of Capri T-shirt nearly every time I observe him delivering my mail. So I'm on pins & needles until I actually get the chips in my hand for fear this guy is going to all of a sudden decide he wants to start a chip collection.

So far so good - all my chips have arrived, however I'm keeping my fingers crossed.
