Hashibashi - does this mean it's okay to place the chopsticks across the top if it's not to show you're finished? I heard that was okay as long as you align them not to point at another person (not across the table). If there's no chopstick rest I'm not sure where else you're supposed to put your chopsticks.

Also I'm not sure how you're supposed to eat e.g. fried rice without yokobashi or kakibashi.

Also! I thought kaeshibashi was a good thing. I've definitely seen people do that at parties.
