These are in Topola, map of which I found here.

The Bog-Watchers failed to provide any cultural references that help us put the pot in it's proper context. Allow me to have a go:
This dual-loader, while presenting a better facility than the conveniences of most Manchester cafés, is still an A-class shit-tip.
The rightmost, presents not only the dilema of co-dumping, but a seatless rim for bottom comfort. Cold as fuck, the temptation to perch above the rim would be great, and you could easily imagine a hand slipping on to a neighbourly-knee.
The left-hand khazi is a tidier affair, but yet no doubt smells of piss and shit.
Between the bowls, a chair is placed for the comfort of third friend, if you simply cannot be apart.
He or She is invited to shit on the floor and a toilet roll has been provided for this purpose.
Overall? A toilet that would be fairly acceptable without the spur of diarrhoea, were if not for the possiblity that someone may sit down next to you.
