The penalties here seem fair and the offender does appear to show remorse – turns out he is himself an immigrant to Britain and appears unaware that in British English “booze” is widely used as a slang term for any alcohol, not just cheap/strong stuff – the use of this term is not a comment on his drinking habits.
She wouldn’t even have known about his previous alcohol problems, and nor would anyone else had he not kicked off to such an extent he ended up before the beak!
Also if the young woman at the shop cannot be named in Court due to her age, she is <18 years old so would have had to call the manager anyway to authorise the sale; that is merely observing our countrys laws, absolutely nothing to do with her faith...
I still get carded occasionally when buying alcohol and I am the same age as him!
