led by circumstance into making do with a jar of grocery store brand instant, i have done research and am informed by wikipedia and the beeb that
for years when i was a kid my dad, american, kept a jar of instant in the cupboard for drinking on weekends, i suppose primarily saturdays, since he drank 1-3 cups a day at work during the week and apparently would get a caffeine headache when he missed it. (i say saturday, because there is coffee at the fellowship hour after church service on sunday.) in retirement i suppose he started drinking instant more regularly.
