i love challenging my estimator.
groceries in a supermarket : for years i’d glance at a pile of someone’s groceries and guess how much it cost.
i could usually get it within $5 for a long time.
i was great at the Price is Right as a kid too.
I think experienced regular shoppers probably find their bills roll to a similar number. $50 for example.
9 =/= 7 ~ 8
