When i was at the Apple store Opera paris people there didn't really know what they were talking about and not to mention nobody spoke fluent English which is pretty unprofessional if you ask me. Thankfully i speak French but i find it still perplexing the closest country to the UK nobody really knows how to speak the international language well enough.
Funny, the Apple Store in Bordeaux always had many English-speaking employees. My French was better than their English, and after a few interchanges they reverted to French, but their English was perfectly serviceable.
On the other hand, it is their country, so I don't think every employee should be expected to speak English.
