The "bull" is Germany's finance minister and the "china shop" is Switzerland.
Excuse me for going slightly off-topic, but it would be remiss of me not to mention what has been the news topic in Switzerland over the last couple of weeks.
Germany's finance minister, Peer Steinbrück, has become Switzerland's most hated man owing to his rather unfortunate comments of late concerning Switzerland's banking secrecy laws, not least his most recent one about the cavalry and the Indians.
In response, a number of restaurateurs and a local supermarket chain in my local area near the Swiss border have now published an ad in the Basler Zeitung denouncing and distancing themselves from Steinbrück's comments. The many comments below the article (in German) speak for themselves.
