Dollar General review: store policy

I visited Dollar General on 08/16/2019 around 6:00p.m. and I purchased a few items along with a alochic beverage, I'm very well aware of the photo i.d.policy, however I was behoove when the cashier Ryan asked me for my I.D. when the Caucasian lady before me bought cigarettes as well as alchol and he did not I.D. her, although he did ask her for her birthday, but never once did he I.D. her...I was also upset at the fact I had to resort to my flipp app to see what was on sale due to the fact nothing was labeled
