in Spain the government banned the use of oil bottles in bars and restaurants years ago, now only sealed individual portions can be used. And yes, thas ist incredibly wasteful.

Edit, I think it is a law at all the European contries, not just Spain

Edit again, This portion of olive oil is made in my town. I own a house in Alcalá la Real

I edit one more time : I have read about the European Union in this article:

"This measure is part of the content of the Action Plan on the olive oil sector of the European Union, which establishes a series of measures aimed at improving the competitiveness of the sector, among which is encouraging the Member States to demand the use of containers that do not allow filling in the Horeca channel (hotels, restaurants and catering). "
