They sell a cup of frozen Ice Cream-Adjacent Dairy Dessert (or whatever they're legally required to call it) with a bit of candy in it for like 5 dollars each.  We're talking like 50 cents of milk and corn syrup.   
  
 They must seriously have some of the best margins in the fast food industry for their desserts.   I don't know about their foray into food, though.

Starbucks has to top this. My old boss told me every drink could be made with 25 cents or less.
