It sounds too absurd to be true, but they are selling olive-oil and olive-oil derived foods and cosmetics.

Anything food-related, cosmetic-related, or even just olive-oil related is likely to have some arcane regulations, especially in the Mediterranean. (I've occasionally heard the olive oil industry being associated with cartels and frauds.) That goes for double if they are – or get confused with – a manufacturing facility which formulates its own products onsite.
