Why don't I receive double gold after hitting lvl 80?

I've been getting less gold for months now from the icecrown daily quests and recently I found that everybody get double amount of gold except me. Basic daily quests give them 15 gold and group dailies give them 42 gold, but I receive only half, even though I hit lvl 80 a few months ago. Is this a bug or am I missing something?

EDIT: It appears that I actually receive more gold than the quest giver says, so it's my bad. The mods can delete the post now.
