Emergency entrance!

How's your French?  I was surprised recently to pass the office of one of my Swiss colleagues and see this sign.

Entree de Secours - emergency entrance!

If you travel in Francophone countries at all you will probably have noticed signs saying 'Sortie de secours' - meaning 'Emergency Exit'.  So this sign for an emergency entrance is both humorous and delightful.  It suggests that if you need help you have come to the right place.

Small note:  The gentleman concerned in invariably helpful too.
