Well said zahavasdad.
I just got back from Austria and when I was there I tooka taxi from the train station to my hotel.
The driver heard me speaking in English and asked me where I was from, I replied London. He then asked me Sie sind ein Yude (are you jewish in german), I replied yes. He then reached into his glove compartment and pulled out a siddur. He explained to me that two days ago he had another jewish passanger who lives in London who had left it in his car. I looked inside the siddur and there was a name, address and telephone number of a man in London. I just got back and will try to return the siddur to him tomorrow.
