Walgreens review: alcohol and cigarettes

Hi. Christmas Eve I went to Walgreens to purchase some alcohol and cigarettes for a party we were having that night. They had to see me ID for both items. Now I'm 71 years old and my license has expired due to the fact I can't drive anymore. (I got a ride from my granddaughter) I was told I couldn't purchase both items. Since when did the age to purchases alcohol go from 21 to 71. I was livid! I have been going to Walgreens for 50 years and never had a problem until now. I have a hard time getting rides from people so this was a huge dilemma.
