Guessing Starbucks is not a job where men named "John" outnumber women.
"John" is still in the top 30 names as of 2016 (ranked 28th) according to the SSA†. It has fallen, for example, from 14th in 2001 when it peaked at 0.914% (18884 births) of the total male births. It was about half that in 2016, at 0.495% (9952 births).
† Numbers vary with region of course. If you've got different data available, please do share.
... Really? Thanks.
