Inspired by that Gizmodo article, I tested the Visa Concierge service to find my wife and her friends some tickets to that Sex and the City movie a couple of weeks ago.
I called and I told them the tickets needed to be at a certain theater brand which has reserved seating, and they called me back when they found a location with open reserved seating.
Probably could have looked it up myself, for about the same amount of effort; however, it may come in handy in the future.
