A matrix perception to detect what is, assuming you're clever enough to mock up a stuffer shack drone ID and spend 8 nuyen on takeout, a delivery drone (Netcat and Slamm-O hacked the delivery system, I can't imagine spoofing a false ID for your use would be difficult)? This bad boy is designed to get up close to someone or something, unleash a tonne of surprise attacks, and then make a decent attempt at escape.
