Waiting for snaps in fog games and crybabies?

So I am playing uckuki in a tournament, 1 vs 1. Arms Race
Normally in a fog, I let my opponent take a snap if I am going to attack him.
Round starts, and by some stroke of luck, I get first turn in all 5 games.
I go ahead & take my turns, but I only attack neutrals that he can not see. I did not attack him once.
There is no 12 hour fog rule.
He gets all bent out of shape and starts berating me for being such a scum bag for not allowing him a snap.
What am I missing here, he couldn't see what I was doing before or after my turns, so what is the big deal?
