one day, the market soya bean drink stall increased its price
and the owner seemed a lot happier even when his "business"
decreased...
i had to explain to my dad why a decrease in revenue may increase
total profit..
profit margin per glass increased... total revenue
decreased...
however, total expenses also decreased..
total revenue decrease is less than total expense decrease =
increase in profits PLUS less work..
i'd tread that fine line too
