Sydney Opera House.

This is the crowd around the Opera House precincts on a Friday afternoon. Most of these people have no intention of attending any function that may be on.
Instead they mill around in their "thousands" for after work drinks or to become acquainted with who knows.
If you need to find your way into the establishment then the "gauntly" must be run and this is quite an experience.
With so many taking photos it's very difficult not to be included unless of course you consider yourself "photographic material".
