It has effect! People are buying less American.
According to Systembolaget (the liquor monopoly of Sweden), there has been a drop in sales of American liquor by 17% this year. This is likely caused by boycotts after the tariffs introduced against Europe.
Long term, this may have an effect on which goods they buy in.
People hoard alcohol? Is that a normal thing? It sounds like an alcohol abuse kind of thing.
If you need to go to a specific store to get beer with quite limited opening hours, you’ll probably get some extra just in case.
Hardly abusive, some go on sale and others I would have for guests. I have prosecco in the fridge for 7 months and a couple whiskeys that were a good price and then some random bits for cocktails if the mood ever does take me.
If I bought everything as I needed it I would have really expensive nights in or missed opportunities.
