A quick note about the Santa Claus thang, worth watching on the merits of utopian thinking, and maybe this will put that handshake into perspective...
The whole problem with anchoring etiquette (or lack thereof) is that everyone seems to have a different idea of what it actually consists of.

So, how far should you anchor from someone?
