I don't know what it is, but when I enter certain shops I always end up needing to take a dump. There's a store here called Marshalls that within fifteen minutes of me going in always sees me in the bogs pushing one out. I was in one yesterday and, sure enough, I was straining away after browsing the aisles for awhile. Thing is, I'd already had a poo at home that morning. Am I alone in this?
