When I was deployed and working in a not-too-pleasant country, we used to have these portaloos that were pretty much just a seat that opened up and then it was straight down into a large amount of blue liquid and, well, the other un-required nourishment that people would leave there. Often you would get an amount of "splash-back", which I was always totally grossed out by.
BUT - when I would finish the job and the associated paperwork, I would often think to myself, if my wallet were to fall into the "poo-soup", how much money would have to be in it before I would retrieve it. Now I'm talking up to your elbow in poo-soup here. . . . . .
Something for you all to ponder. . . . .
