not me, if i'm cooking, its cooks perks to have the egg you havent broken, or the unburnt bacon, as i know it would be the other way round!
I always take the smallest portion, but thats because im not really hungry (plus, i AM the "smaller portion" out of the two of us!)
If i dropped something, i would always wash it off and give it to the other half!
the only concession we have is that if something needs to be cut into 2 portions, theperson who cuts is not the person who chooses - this gives the cutter incentive to make them equal!!
