I would go along with that point if best before was related to food safety. As it is, it seems to be far more related to appearance. Yogurt separates. Stir it and you are good again. Print the date around the time you expect mold, printing it around the time of separation is the problem they are trying to fix with millions of tons of healthy food in the garbage.I think for perishable products a BB Date is a pretty good thing. Did not say perfect... Many exceptions, both in products and the people that eat them...
