I am not familiar with Mr Atkinson's company premises but, if I know electricians, I would wager that a few walls will also have the odd saucy calendar or porno pin-ups decorating it.
Of course, that's all OK....but when it comes to a palm cross in your van or wearing a crucifix chain...then it's you for the high jump!
So maybe we Catholics should fight back and show some solidarity with Mr A. You do see one or two cars with a rosary hanging from the rear view mirror however, I don't think that is particularly good. But a rosary or small crucifix discreetly bluetacked to the dashboard might be a habit worth cultivating.
That does provide me with one headache, however, do you think that a four foot high statue of St Therese de Lisieux is a bit OTT?
