Not seen any when I was working there, and being therein after.
Yep, just after I was mocked for drinking cider, "blah blah bottom of the park with your friends when you were 15 wah wah"... Never did it personally, I only started drinking properly when I was 17.
It's cheap, it's strong[ish] and doesn't taste that bad either. A 2 litre bottle of Sainsburys "Strong" Dry Cider = £3. I could spend more on a 4 pack etc, but I don't see the point.
