I was waiting for my food in my local Indians a couple of years ago when I woman came running in holding her bum and she asked to use the toilet. The owner said he couldn't let her use it because of some insurance issues but before he could finish talking she said it didn't matter now and she walked out leaving a smell of poo behind her. When I got my food and walked around the corner to where I'd parked my car she was leaning on a sign. Her jeans had a wet diarrhoea stain spreading in the the back and down her legs as she continued to go and I guessed she must have eaten something bad earlier.
