The non-TSA pre-screeners at BOS are rudest people you will ever meet. That being said, last Christmas I got a good laugh from one. We were on our way into the security line for terminal B and the lady was checking ID and boarding pass. This was at about 445am:

PAX in front of me: (gets up to the checker) *blank stare*
Checker: (in broken english): "boarding pass and id."
PAX: *looks at her as if she is speaking klingon*.
Checker: "Boarding PASS and ID"
Checker: "BOARDING PASS and ID Sir!"
PAX: *pulls out receipt from CVS and stares at it*
Checker: *fustrated* "Git de' hell out of the way"
Checker: *motions to me* "Boarding pass and Id please? "

I laughed all the way to the gate.
