There is little worse than having Crohn's disease and being in immediate need of a bathroom and having some store clerk refuse to allow it. I've been left standing in front of that clerk, in complete misery and pain, terrified that I would lose bowel control before I could find another, more friendly spot. Loss of bowel control is a real fear; it could, and has, happened. It isn't pretty. It's humiliating. I wouldn't be asking if it wasn't urgent and necessary. It isn't my idea of fun to have to use some filthy room stocked with mops and buckets and NO toilet paper, I do it because I must. Having a law on the books allowing me access to a toilet in my moment of desperation is my idea of right.
