I don’t know how it is where you are, but here in the UK there’s a startling lack of public toilets. OK, it’s the not the most glamorous of subjects (but then nothing IBSy is really) and you won’t get rock stars making a single to save the toilets, but they’re pretty important.
Without a good network of loos across the country there are whole bunches of people who can’t leave the house – IBS people, colitis people, IBD people, people who are nailed to their carpets (although people who are nailed to their carpets probably deserve all they get).
And just one bad experience, where you’re desperate for the loo and there’s none to be found, can make it harder and harder to leave the safety of home. And then you never go out, and then you get more miserable, and then your IBS gets worse, and then your canary dies.
You see how important public loos are?
