Hmm. Interesting idea, but I'm not sure this is the scenario I'd pick. Sitting in a restaurant overhearing slightly annoying fragments of other people's conversations, can't eat any of the restaurant's food, can't leave because it's raining too hard, so you spend three hours hanging around doing nothing.
A friend has a TV with a screen the size of a single bed sheet -- that would help put you into the scene even more. Within 10 years people will be doing it with virtual reality, the way they do now by looking through goggles.
