Australia? Missed that part. A quick tale from camping in that genteel land.
A couple slope off from the campfire. Just as they pass into darkness the lady calls out:
Ahh shit bags, I forgot I'm on the rag. You'll have to crack us one up the shitter.
My crapper is not in the bathroom so the problem doesn't arise.
That said I'd try not to but if I had the urgent need to vacate my bowels I'd expect anyone brushing their teeth to evacuate the area. After all it's a lot easier to spit in a cup than shit in one.
