Some people find waiting for others unacceptable. And some are unable to understand how someone can think not waiting is ok. And neither side is going to change their mind.

This problem can only be solved by SE at this point. By taking away the choice of skipping or not.

Just out of personal curiosity: if someone is slow in the supermarket in front of you (at the cashier). Do you wait or try to jump ahead of them so you don't have to wait? Do you apply different ethics to a game because there are no lasting consequences/can't see the other human?
