What is Bobo's definition of the "all-purpose luxury" while living in Africa as noted in the memoir, Don’t Let’s Go to the Dogs Tonight: An African Childhood?

Coca-cola is the all-purpose luxury in Bobo's Africa. It is drunk hot, straight from the bottle, because there is no ice or refrigeration. Coca-cola is considered a special treat, and a cure for dehydration or diarrhea. Border guards are often bribed with cash, cigarettes, soap, cooking oil or Coca-cola.
