Yes, phones are mobile and everywhere now. But before that, public phone used to sit inside a booth... and before that they were also out of the booth. People would take the phone and put your head inside this kind of device encountered at CERN the other day (te gent on the picture is Mr. Woebken).

Why do I blog this I wonder when this sort of protection will be re-installed in cities. A a sort of place where it's convenient (and acceptable) to make a phone call. It reminds me of the use of cell-phones in public phone booth.
