the Westfield Center, put up banners in Arabic script welcoming people to London, and quickly took them down again. I say "in Arabic script" because no one could recognize it as the Arabic language. If you read Arabic, look closely at the above.
It takes a while. First, read it from left to right, not right to left. Then, of course, the letters are not connected to each other. But other than that, it reads "Marhaba bikum fi London," welcome to London. .sdrawkcab tsuj s'tI (It's just backwards.)
It doesn't rise to the level of showing the South Korean flag while introducing North Korean athletes, which miffed the North Koreans (who tend to be very miffable) no end. But it does raise the question, doesn't anybody proofread this stuff before it goes up? It's not as if there are no Arabic speakers in London. And somebody bothered to get the phrase translated (correctly) but didn't know Arabic goes from right to left?
On that note, let the games begin. And let us all ponder this question: in Ancient Greece, did the Olympic Games have an official shopping center?
