A Balinese ‘dunny’ is a traveller’s worst nightmare – and the worst of the worst is probably one you’ll be asked to pay for! I’ve frequently seen stalwart companions-in-need get just inside the door (often just an opening in the wall really), do a U-turn and exit without perceptible pause, looking pallid and strained.
Never approach them in bare feet or with only thongs or flip-flops on. Can you use a toilet with only one hand? You will have to because your other hand will be needed to hold your nose. And don't ever contemplate sitting (on those that are of Western design)
Don’t think for one minute that nice shops, department stores, or even hotels at times, will have anything other than DUNNIES! Above all, don’t expect toilet paper. ALWAYS take your own toilet paper for emergencies. It’s as important as money as soon as you leave your hotel. And remember your dear old mother’s advice, "Always go before you leave home!"
