if adults have to be slightly inconvenienced in proving their age to buy one in a shop, then so be it - the extra ten seconds to pull out their driving licence or other ID and show it to the shop assistant is quite a small price to pay, no?^

Agreed but to clarify for non UK people reading, when you say “have” to prove “their age to buy one in a shop” you don’t mean, “cannot buy without an ID” in the UK. Once you get to a certain age where the retailer can see you are clearly over the relevant age, they won’t waste their time, or your time asking for ID because of common sense.
