Well honestly the only time it bothers me is when someone crosses the room to get a clam right in front of me while passing ones that were closer to them. lol sometimes I think it is reflex more then anything. But I have had to leave the room after getting really angry at a clam swipers and no game is worth that.
I totally understand what you're saying. I think people who go for shells far from them, under the condition that there are ones close by, are
usually inconsiderate (I say
usually because if they are in an area with many people, so selecting a far clam gives them a better chance of getting credits that round, so it is reasonable).
About you having to leave, I'm sorry that you got so angry. But that shouldn't be a reason for people to not be allowed to go for the shells that they want to go for, if that is what you're implying.
