Oh dear, nothing wrong with eating left overs, we never had any as a kid, too poor! Couple of days as said, in fridge, no problem.
What really annoys me is how much food is wasted by Supermarkets in particular. The other day a woman was complaining to a member of staff that the food she wanted was past it's sell by date, hadnt been removed from the shelf and she couldnt get any because it wasn't fresh.
Fresh....so much comes from the other side of the planet, is stored in deep freeze and goes off quicker than that.....but they say it's fresh. As for the woman in the store, I was so tempted to remind her of all the starving millions in other parts of the world...but didn't because I was too cross. :/
I think I'm in a ranting mood today, this is the second thread I've gone off at a tangent ranting.....sorry!
