When I was in England, around age 20, I attempted to buy a fish pie in a grocery and was asked for ID. It was the checker's first day and he was confused by the pie filling being mussels in a wine sauce. His supervisor, a kindly woman who looked like the cop* in "Broadchurch, " came over and put the young bloke's mind at rest, that I could not get inebriated on wine-based sauces and did not need an ID.
