I see this behavior quite a bit as well. They sit outside a local KH located on a busy street and talk to each other. I visit the shopping center right across the street from them and sometimes I sit there for a few minutes watching them. Plenty of people walk by and often they are too engaged in their own conversations to even say hello. I doubt this behavior is encouraged or expected from the GB. But many dubs are probably relieved to not be bothering people at their homes. And more concerned with their own little jdub lives that it is easy to sit there and chat about all the exciting new changes coming their way.
I will say judging from the outside this is one KH that could probably use a renovation or new location. It really is a very busy street and a little kid could easily run off into the street. This happened years ago when i was a small child. Our KH was on a very busy street and a little boy ran out from the KH and was killed on the night of the memorial. I believe the guy was a study. Very sad. I will never forget it.
