About 20 years ago, I tried to order a sandwich at Subway and got into a very minor confrontation with the server because I didn't understand how the whole thing worked. I still think about that sometimes. I don't understand how Nando's works either, so I've been careful to avoid the same mistake and have just never gone in.
BTW: your Community only allows posts from 'Unspecified' as a language. The standard thing, I think, is to multi-select both 'Unspecified' and 'English' in your Community's settings.
