Here is an interesting blog post I found on the web.
I could not find a reference for it anywhere on our forums
http://julesritter.blog.24heures.ch/p4.html
The topic is a bit old, but interesting nevertheless. Have a read.
I found the comments much more interesting. It gives a unique perspective, because on the englishforum, we have mostly expats and not enough Swiss nationals posting.
Cheers,
