A&P takes your birthday for beer
Nice to know. My response would be to cover the month and year of birth with a piece of tape, leaving only the year of birth. One might also cover one's last name, or perhaps first and middle names. At need, one can lift up the tape, but for identification purposes, the photo and year of birth ought to be sufficient to buy beer. They need to know you're 21, and that's all they need to know.
