It went like this:
I, in garbled French, try to explain that I am a fan of whole wheat bread and something with onion or olive as an extra.
Mr. Fou, in clean English, who understandingly and patiently shows the composition of the long loaves and, look, small rolls with olive tapenade and onion!
I can say with some joy that my wife is gluten intolerant and I, an onion-olive roll and 2 shells of bread with Farine de Seigle later, will return later this week.
By the way, I had never seen one-meter loaves of bread sold by the kilo.
Rock-solid bread!
