"The ketchup packet is one of those things that has stayed exactly the same since before I was born. After all, it fulfills the duty that is required of it. It holds your condiment until such a time that you're ready to add it to your food. Well at some point Heinz decided that they could do better, and undertook the task of reinventing the ketchup packet. The end result was essentially a cross between the old packet, and the little plastic containers that you get BBQ sauce in at McDonald's.
It does seem to make perfect sense. When you grab a burger and fries through the drive-thru, where do you put the ketchup that you're going to dip your fries in? Maybe on a napkin, or even the wrapper for your burger. Either way, you're increasing the risk of somehow getting it on your clothes. Now you can tear off the whole top and dip your fries in, or just tear off a part of it and squeeze the ketchup onto your sandwich. So simple, yet so brilliant."
