What Was She Using It For?

An old lady at the grocery store today was buying 8 quarts of half and half. Let's play what was she using it for?

• Ice cream, the hard way (she wasn't buying any sugar though, so maybe she has tons of that already).
• Bridge tournament hostess
  
• Very large family which all likes coffee
• She just likes to drink it?
• She thinks it will keep for months and months
  
• Bad-milk-related practical jokes
• Low-quality Camembert
• Senility (theory supported by her other purchase, a gallon of vinegar)
