I'm not too sure it was that laid back at the latest Lugano-Kloten game mind you...
It really depends which game you go to see, the last Bern-GSHC game I attended, a few week ago, you had the riot police inside the ice rink and my wife had an interesting experience at an earlier Bern-GSHC game, being from Wigan, she found it very funny mind you...
Best games in Swiss hockey are:
Fribourg-Bern (and vice-versa)
GSHC-Lausanne (and vice-versa)
Ambri/Piotta-Lugano (and vice-versa)
All three regional derbies...
