Can't someone develop genetically modified tangerines that have a big cross on the outside if they're going to taste dry or bitter and then not grow those ones? Sometimes they can be a delicious juicy treat, sometimes face-scrunchingly rank, and you just don't know what you're getting until you peel it and bite into it.
And don't get me started on when you get one of those weird chewy Maltesers. Crashing disappointment, especially when it's the last one in the pack.
