tea, ISO standard cup of

tea, ISO standard cup of n.  [South Africa] A cup of tea
   with milk and one teaspoon of sugar, where the milk is poured into
   the cup before the tea.  Variations are ISO 0, with no sugar; ISO
   2, with two spoons of sugar; and so on.

   Like many ISO standards, this one has a faintly alien ring in North
   America, where hackers generally shun the decadent British practice
   of adulterating perfectly good tea with dairy products and
   prefer instead to add a wedge of lemon, if anything.  If one were
   feeling extremely silly, one might hypothesize an analogous `ANSI
   standard cup of tea' and wind up with a political situation
   distressingly similar to several that arise in much more serious
   technical contexts.  Milk and lemon don't mix very well.
