I will preempt this by saying I live in Scotland and am basing this on what I’ve seen. I cannot answer for the rest of the uk. 9.15am and I’m in my local supermarket this morning picking up a few bits. I spot my friend who works there putting a bottle of wine back on the shelf and she says that is the third bottle she has had to put back since the shop opened at 7am (Shops can only sell alcohol between 10am-10pm). The customer is complaining about stupid Scottish rules. Monday they refused to sell alcohol to two people mid afternoon who were heavily intoxicated and Tuesday they had to ask someone who was drinking in the foyer to leave. This is sadly something I have noticed not just in that supermarket but others across the city and that this is a snapshot of a wider problem.
