Personally I have observed that some people who work remotely suffer from delusions as to what happens in the office when they're not there. They'll scoff at the lack of progress of the office workers, compared to their own majestic productivity - ignoring the fact that someone needs to be back at base coordinating all of this stuff, dealing with customer situations, walk-ins from product managers and execs, etc. etc.
A further elaboration of this is when remote workers expect to impose some kind of extreme rigour on their unfortunate office-bound colleagues. They might insist on 24 hours advance notice of important design discussions, which could otherwise take place at the water cooler, just to be sure they can be included.
When told thats not the way the world of work works, they may play down the effectiveness of the water cooler discussions, when most people have observed first hand just how beneficial those serendipitous hallway meetings can be, and how detrimental it can be to have to delay important discussions until the remote people can be involved.
