I don't live in the USA, where the beer can gets a sock put over it. The collection remains open. Why should it disappear behind doors? Teenagers only have alcohol that they chug in masses. They are still far from enjoying a drum slowly, pleasurably, with all senses (eye, nose, mouth).
I think flaunting schnapps, even if it is higher-priced, is something for teenagers.
If now and then a "non-age-appropriate impulse" contributes to one’s own and some others’ enjoyment, related expressions of disapproval are sometimes easy to endure.
