Synaptic Snaps, Crackles & Pops

The closest real-life living-in-a-building experience I had was Reception Station at Army Basic Training and one Army school. They were open bay situations, but there were plenty of useful appliances at the end of the bay. This scenario was a real deal during field exercises, though. You're in a sleeping bag, in a tent with at least 3 other people (at least 3x that, if the tent is a Medium), it's cold, it's the middle of the night, and you wake up because... It's quite the endeavour to get completely dressed - including your tactical gear and weapon - and make your way to the nearest porta-potty without a) waking anyone in your tent, b) tripping over anything along the way, or c) taking too long to divest yourself of enough of what you're wearing to do what you came to do.
