Thank you for this nice thread! My question: what is Wayland all about? Why would I want to use it and not any of the older alternatives?

Maybe they have one machine set up to fill the bottles. In one market they are required to deliver a safety margin of 3%. So they put 618 in a 600 bottle. In the other market there is no such requirement. So they write 618 on the bottle.
