I've met a "drinks cans" compound noun on this webpage.
See how food and drinks cans get recycled
As I know, there is a specific rule for the plural compound nouns that are made of two nouns. In this case the second noun takes an -s form and the first one acts like an adjective, so it cannot have the plural form. "Drinks cans" is not a typo, it is also pronounced this way in the video, so how can it be correct?
