Okay, I see this done several different ways and I'm trying to figure out what is actually correct. 

When the round is over and you shack hands with the people in your group.  Do you remove the hat or do you keep it on?  I see this being done both ways and I'm trying to figure out the meaning behind this.  Is it more proper to remove the hat or is it a sign of showing respect if you lost the round? 

So if you have any thoughts on this, please let me know.
