Can I have a P please, Bob?

There was a time, when I didn't really need them, when there were public toilets all over the place. Now I'm getting old, and my bladder is not what it was, you're hard pressed to find one, and even when you do, the state of them leaves much to be desired. So thank goodness for supermarkets, and I'm all for this idea of getting cafes, pubs and restaurants to permit passers-by to come in and use their toilets. To quote the Bard - for this relief much thanks.
