My beer bottle tells me not to drink when driving and not to drink when pregnant but it doesn’t tell me how alcoholic the content is. When I bought the beer, I had to tell the cashier my month and year of birth when I am clearly, very clearly over 21. But beer bottles do come in matching carry cases, so I can look stylish whilst kidding myself that someone thought I looked young and falling over drunk because I have no idea how strong the beer is. Cheers!
