paper napkin with dodgy English translation

It would make sense for ‘Volte sempre’ to be translated as ‘Come back always’ in English.  But, as we know, translation is not that straightforward and an English native speaker would know that this is not correct in English.

A more appropriate translation would be ‘Come back again (soon)!’

This is why it is important for translators to be native speakers, or at least native bilingual of the target translation language.
