Dancing and ear plugs

It is slightly discourageing being a musician in Switzerland, I imagine. I have observed on more than one occassion that dancing is not common practice at live concerts, and the wearing of ear plugs is recommended. Now, I may be alone in thinking this, but if I were a musician and I had scribbled songs for hours, tirelessly practised my chords and so on, I would be pretty peeved if punters turned up at my gigs with bits of foam in their ears. And trying to encourage the crowd to clap or to dance is as challenging as drawing blood from a stone.
I have to say though, that those who do dance and clap and ostensibly enjoy themselves are not frowned upon, although you do get a few smiles that could easily pass as sympathy smiles. It's sort of "Aww, bless them having a little bop, don't they look silly. And oh, they're not wearing ear plugs - they'll regret that when they're older."
As a fan of bopping along (usually out of rhythm, but that's not the point), I see live music as an opportunity to wave your arms in the air, wiggle your bum and generally let the music into your body through your ears. Maybe the Swiss have extra 'listening' holes and can therefore afford to block their ears with foam.
Hmm...now I feel like I'm missing out on something!
