Nominative Determinism*
With a name like Decaux, it was inevitable the family would be into outdoor advertising.
One might expect that their signs should be displaying nativity scenes at this time of the year, as in "Come take a dekho at JC".
But arguably there is no Christmas in Hinduism, hence "no connection".
*The funniest example IMHO being Splatt and Weedon, who were apparently prominent urologists.
While I am here, let me wish all commentards a Happy Gregorian New Year.
