You could tell this from the furiously furtive wrapping activities and mince pie production-lines and excited children pretending to be well behaved whilst sneakily stealing chocolate baubles from the tree.  Whilst I’ve never uttered ‘bah, humbug’ out loud, Scrooge’s words do reflect my feelings about being comprehensively ripped off by myth-making so flexible and so divorced from its origins that even Tommy Yaxley Robinson Lennon can seek to exploit it with some level of impunity.
