Why not offer the multi-lingual set-up from the beginning?.

I think this would be better for many colleagues operating in very large markets of their own.

The obvious additional languages would be:

Spanish

Russian

Chinese

And this would just be three additional languages. I don't think there is a need to add other languages such as German, French, Polish, etc. even though they are representing big populations and a lot of shopping centres and retail power.

At least the menus could be in those languages.
