What a load of bollox.My alcohol purchasing habits are very different in supermarkets v off licences. If I ever want to buy a load of drink I go to an offie, because everyone else is doing it and I don't feel judged.
But in a supermarket I'd only ever buy a few bottles of craft beer and put them through with the rest of my groceries. Always the risk that you'll bump into a work colleague or an old teacher in Super Valu, so you don't want them to see your trolly full of cans. If you meet in an offie though, you're there for the same reason and it's all good.
If they close the offies youd probably set up a tent outside the supermarket so you're nearer the supply.
