Thick creamy yogurt is not the norm for South American households; it's usualy runny, or "bebible" as they call it ("drinkable"). In the hotter months, this consistancy didn't bother me because I just threw it in the freezer and had a thickened yogurt smoothie, but now that it's cold outside the only way to have yogurt is the drinkable way.
I suppose the consistancy is something I can get used to, but the packaging is something I will never fully enjoy. Liquidy dairy substances, like milk and yogurt, are always sold in rectangular plastic bags. Once you cut of the tip of the bag to pour yourself some milk you have to put the bag in some sort of container or it will spill everywhere (unless you can drink 1 Liter of milk with your coffee every morning), and sometimes it will spill everywhere just from the pouring, if you don't have your skill just right.
In addition, the plastic bags aren't very sturdy. I always see some poor grocery store employee mopping up milk spills in the refrigeration section. I bet s/he wishes Uruguay had cartons for their milk too.
