Sorry -- I misremembered the story. But as another commenter notes, it's routine for women to not know they are pregnant [0]. So my claim is not "absurd", and I don't feel any need to "reflect" on my actions. The patronization is not necessary.

The main intent of my anecdote is to show how retail companies are already analyzing data. And I think it's foolish to assume that we (i.e. people working directly in tech) know better than the people who are working in tech + retail. (Many retail stores are on the technical bleeding edge - Target spins up K8 clusters in each store [1]!)
