You know, that actually isn't the worst idea! Putting tangible results of the EU on the Euro would constantly remember people that the EU isn't just some nameless and faceless bureaucrats doing busy-work in an office building in Brussels.

The cookie notification is of course a bit silly, but a "Thanks to the EU you'll never lose another bottle cap" or a "This standardized USB-C charger is brought to you by the EU" would do wonders for its PR.
