In the little town of Hautvillers, we saw two things of note, one of which struck us as typically French, the other as counter to almost everything similar in France that we had encountered before.
The Champagne tasting and sale shop, at 3, rue Dom Perginon proudly annouces that it is open, amonst other times, 10h30 - 18h00, all week except Mondays, all year with certain exceptions November - March. Except, apparently, right when we were there. Very French.
The public toilets were exemplary. Clean, spotless even, accessible, and with the gentlemens' urinals shielded from prudish view by batwing doors. Clearly catering for tourists who expect nothing less, especially, I imagine, our American cousins. Not French at all.
