Okay, my search fu has failed me once more. I think I need to upgrade my skill wires.

So I call upon the unstoppable force of dumpshock. At some point in the past I stumbled upon a free PDF for a SR4 mission that started with the PCs browsing a stuffer shack, down on their luck and spending the last of their nuyen on something to eat before an explosion went off. I don't know where this PDF went, and if anyone has a link, I'd give them all the
Stuffer Shack brand Nutrisoy Brownie Bars they could ever want.
