Paris has launched a new kind of tourist guide: not a guide for tourists, but a guide to different types of tourists.
The intention is to encourage the legendarily gruff Parisian hotelier, waiter or taxi driver to be polite to foreign visitors and not to assume that all nationalities enjoy the same things on their holidays.
How useful the guide will be is open to question. British visitors, it suggests, "like to be called by their first names". Britons, it goes on, want all their activities to be "playful". "Les Anglais", the guide says, insist on eating at the absurdly early hour (for Paris) of 6pm to 7pm.
The Paris Chamber of Commerce and Industry and its Regional Tourism Council have issued a booklet and created a website for tourism professionals called Do You Speak Touriste? The intention, according to Jean-Pierre Blat, the council's director, is to make sure that foreign visitors are not inadvertently insulted.
"One does not welcome a Japanese and an Italian in the same way," Blat said. "You have to adapt." But the reputation of Paris as an unfriendly city is undeserved, he insists.
