Years ago, while on active duty, a coworker and I travelled from Europe to the US for a training class. Not only did the guy buy a very expensive carry on/laptop bag at the airport, he saw a watch that caught his eye. On our return trip, he purchased the $3000+ Tag Heuer. Craziest airport purchase I've ever seen.
Later, he complained that he was having trouble registering the purchase with Tag, as it wasn't at one of their recognized vendors. Beautiful watch, but I'm pretty sure it tells time just as well as mine.
