Friend is getting normal gold rates from quests despite being level 80

We're playing on icecrown, my friend hit 80 so I thought I'd do quests with her in order to get fast gold, but for some reason she keeps getting normal gold rates as the quest reward says.

for example, if the quest reward is 12 gold, she is getting 12 gold while I'm getting 60 gold, does anyone knows why is it happening?

Thanks in advanced.

did she disable experience gain at the twink experience eliminators

No, and neither did I, is that necessary?
