1. In Pennsylvania one time at a beer store. Had my 18 year old son with me and my brother in law. Grabbed two 18 packs and had my son help me carry one of them to the counter. Tiny little place 20' x 40' or so. He set it on the counter and I went to pay for it. They asked him for his ID and when he said he was 18 they immediately kicked him out of the store and berated me.
2. I was in a little convenience store in Maine, I bought an 18 pack and 2 of my sons were with me, 19 year old, and 17 year old. Clerk wouldn't sell the beer to me because my kids weren't 21. Finally she got the manager who let me buy it.
3. My buddy and his wife were in Walmart, he was 43 and she was 41 at the time. They had a cart of groceries and in it 2 bottles of wine. Clerk asked him for his ID which he had, then asked his wife for her ID. She had left her pocketbook in the car. Clerk refused to sell it to him because she didn't have her id. They even called over a manager and the manager refused to sell it to them also.
Nothing surprises me anymore.
