This may date me, and that's fine, but when I started gaming you could be thrown out of a gaming store for touching another person's dice without permission. I'm not sure if that trend is still in place, but people in general seem less concerned about character sheet sanctity and are more free with their dice than I remember from my early days.
With that in mind, I am curious as to how you and your group handles dice etiquette. Does everyone have their own set of dice? Does one player share his with everyone? Is their a public pool? Is it considered a faux-pas to reach over and grab someone else's die without asking?
On the more technical side, is it cool for one player to do the actual rolling for another player, or does everyone have to roll their own checks?
Finally, do you think any of this has had an impact for the feel at your table?
In my regular groups, we usually do D10 based games, and there is a jar full of D10s that are used as public dice. These dice have all either been repurposed, or specifically bought, to be a public pool that the game as a whole can pull from when they want. Aside from that though, people do borrow dice fairly freely when needed - though you still ask before taking someone else's die.
I'd like to think the shared pool has helped with a general shared feeling at the game table, but I'm not sure if it would matter with this group. The group as a whole is just more open and more 'group oriented' than the groups I played with where touching another man's dice bag was akin to sleeping with his wife.
How about you?
