Dd16 tried to buy a latte from Costa earlier. Apparently the man serving asked how old she was as he's not allowed to sell caffeine to under 18s. She got the coffee as he said 'just this once but he wouldn't be able to sell it in future.
I asked if he was joking and apparently not. Is there any truth in this? I know there are restrictions on energy drinks, but never heard of anything like this.
