While the paying for the restrooms used to really bother me, I have finally started to admit that those restrooms are usually cleaner then the free ones. But with a group of 11, go for the free ones, just have plenty of anti-bacterial products handy.
What do you mean by 'Free bathrooms'? Is this a part of advertising program or what? I'm confused.
What I mean is that you don't have to pay to use the restroom at this supermarket. In much of Europe it costs money to use a public toilet.
