What a peculiar usage of whole milk. The great mind would suggest the idea stems from the flavors of a "root beer float" in a easier to consume flavored whole milk form. What an interesting price to behold, it is highway robbery of the nicest order.

While I don't encourage adding fish sauce to milk. I appreciate you using whole milk yoghurt for such an interesting and refreshing dip.

Skim milk removes a lot of the vitamins, minerals, and fats that make milk a nutritious "meal" that you can drink.
