"but it is harder to find one now as many round here have been shut."
Exactly. Before I had an operation, last year, I had to wear a catheter, so had no "desperate to go" moments, and having moved to a new city, took a few hours out of my day (in fact to see what laptops there were, for someone asking on MN) to go off to another part of the city to explore a retail park, and walk back.
I walked seven miles through various suburbs, saw the odd collection of shops, a few places I won't likely ever wish to see again, and apart from an Asda store that was open, which I did pop into, but not to use the loo, can distinctly remember not seeing a single public toilet where one might be able to "go". Additionally, on that 7 mile walk, not a single park bench (and I walked through several small and one large park). So "green" the city may be, but facilities are definitely lacking.
Obviously there may be Asda, Tesco and so on if you were in a city or town, but public toilets are nowhere to be seen around here.
Yes, blame it on vandalism, government spending cuts, or whatever, forcing local councils to close or remove them (or in some places such as where I lived in N Wales, add one of the 20p public toilets with the doors which open automatically after a certain number of minutes, like it or not!) but I'd say the chances of finding public toilets in many areas are getting fewer and fewer.
I was going to start delivering some leaflets for my own business (if I can get enough people to switch internet I could give up "working" for a living) but the prospect of 3-5 hours wandering the streets with no public toilets makes it change from "healthy exercise" into a "toilet nightmare" !
I'm not advocating deliberate use of a bush but if you've got to go, then I'm afraid you've got to go, and I'm not going to criticise anyone who just cannot "hold it". Maybe I'm nore forgiving now I'm getting much closer to retirement age than you youngsters!!
PS For she who should have name changed, yes, it might have been an idea, but frankly it's public now and getting the post deleted would make it obvious anyway :) Anyway, you're only human, and it could happen to any of the "absolutely disgusting" brigade this time tomorrow or next month or in 20 years time, so don't worry about it, your secret is public knowledge safe with us.
