When I was in college, my friend and I were at a sub shop. I had severe colitis at the time, and my friend was aware of my potential emergency bathroom access needs. I asked, "do you have a bathroom," response, "not a public bathroom," and my friend sternly said, "he didn't ask you if you had a public bathroom or not, he needs a bathroom NOW!" and that was successful.
I was in Pennsylvania on business and met a guy with Crohn's disease, and we discussed urgency issues. He told me there was a law in Pennsylvania, Restroom Access Act "Ally's Law," that a person carries a card and when a business is shown this, they must, under most circumstances, provide access to employee-only bathrooms.
Not sure if this has been a topic before, but this is AWESOME! It is a law in many states and, of course, it is valuable for our friends with any IBD, j-pouch or other intestinal issues. This is not valid in NYS, but I plan to present this to my local representative.

Hope it helps! Way to "GO" (!) Ally! Read about Ally's story -- we can all relate!
