Early Pulling - Is it wrong?

[Hasrat]

But to think someone should have to wait or could be reprimanded for not waiting is absurd.

Actions have consequences. Community standards and all that. Just because there's no explicit rule doesn't mean players can't take their own actions against it (within the rules).

There's no explicit rule that says you can't cut in line at the bank.
There's no explicit rule that says you can't steal that old lady's parking spot that she's been waiting on.
There's no explicit rule that says you can't drive 50 in the fast lane.

But if you do you're going to be viewed as a dick and treated as such.
