It is not 2 but 1 - you receive begging card for each food missing. So in fact this card will give you max 6 food ... For me it is a weak card...
Not only that, but if you seriously attempt to get the max six food out of it, you are constantly in danger of starvation if something goes sideways. It's actually a little bit of trouble to always hit -1 at the end of the feeding phase. Changes when you have to bake bread or slaughter animals so that you don't end up with extra, which would force you into suboptimal moves. It also normally means that you'll start the next work phase with zero food, which may be a problem if you were going to do anything involving spending food.
I dunno. If this card simply gave you 6 food, I wouldn't be very excited about it. But as it is, it seems terrible.
