Working in France FIMO

Simon:

Gidders:
When I lived in Belgium (Flemish) they spoke 70 as septante rather than the official soixante dix. The French appear unruffled by this.

Belgian French for 90 is Nonante.
Isn’t Flemish (Flems) the Northern language, similar to Dutch?

Flemish is indeed Dutch with a noticeable accent. A bit like Geordie English ?
