As a young teenager ( a thousand years ago) I was part of a Friends of the Earth protest who climbed over the wall of the Schweppes factory to return their non returnable bottles.
All fifty of them. It was a right faff an' all.
Not so much a green protest as a How Very Dare You Make Them No Cash Back protest.
Greta Thunberg has nothing on young me!
