Lots of cafe's (including McDonald's) will charge you money to use their toilets even if you are a paying customer (different if it was to deter people popping in for a Mcwee). Shopping centres/train stations all charge for toilets if they have them at all and even large supermarkets don't tend to provide toilets. So you are completely stuffed if you are out in public and need a wee.
I found the same when I visited Belgium. I really think it's outrageous because it is such a clear-cut case of sex discrimination - men get public urinals, women get nothing at all. Even in London, you now have these urinals all over the place - obviously a good thing in one way because it stops men publicly pissing in the street, but why can't women have toilets too?
It also affects people with bladder or bowel dysfunction (quite a large group) and, as it says in the article, people in wheelchairs. And yet this huge, obvious injustice, which leads to some people feeling unable to venture out in public, hardly gets discussed.
