I suspect it's not uncommon to find people who have wine nearly every day. Someone who is drinking two beers on many days is likely to have six on some days, making up for the odd day that they have zero.
The actual quota is less than one can per day, though, which seem too strict to me (with respect to a government restriction, I mean).
It’s not in the UK at any rate, the average varies between 12 and 17 units of alcohol per week depending on age with most of that falling on Fridays and Saturdays. 2 cans of beer per day works out at 28 units, so is certainly substantially more than average. I would guess there is a bubble affect though, most of my friends drink only on special occasions line parties, and regular drinking at home would be perceived as alcoholic behaviour by most of them.
Well either its has changed since I lived there or your friends are not big drinkers. Regular drinking was not seen as anything out of the ordinary in the west country and London.
Editing to add - it is a good thing if it has changed.
Depends on culture, both national and local. In some it's very common (like my dad has a beer every day after work, or France / Italy where a glass of wine at lunch is not uncommon).
Light wine was specifically exempt from the rules
There was a post here where having a cocktail after work every day (in NYC IIRC?) was mentioned, the consensus seemed to me like that is a normal amount while for me that would have been too much even when I was a student and could tolerate a lot more alcohol (of course, purely by amount I’d have made it up on the weekend).
A glass of wine after work to wind down is pretty popular no? (Culture: scandinavia)
