What's the general rule for Public Shitters. Although reports are inconclusive, studies have shown that people sitting on outdoor crappers have a tendency to fart much louder than indoor ones. Personally I try not to use em unless I have something nibbling on my draks but even then it's a toss up between squeezing the cheeks and a fast ride home or sneaking into a public one and doing the business there and then. Interested to know for my ongoing poop research !!
