Yes, I've heard of this too. Today during Tommy's match, the commentator mentioned this story that a French TV team who was supposed to do a report about Nadal came to the wrong "Halle" in Germany. And when they arrived at the right location, Nadal was already away because he lost first round.
Of course it must have been twice as painful for this media team that they first went to the wrong Halle because Halle/Saale is in East Germany and much more further way for them coming from France and it was misleading because Halle/Saale is actually the much bigger city of the two (250000 inhabitants). Halle/Westfalen only has about 20000 inhabitants, but still hosts this great tournament
