Most of the time, I expect to be carded whenever I would be purchasing alcohol. Say, ordering a drink in a bar or a restaurant for example, or buying wine in a liquor store. However, these are inconsistent. Sometimes, I get carded, sometimes I do not. In occasions where I expected to get carded, for example, when I bought a Riesling for a dinner a couple of weeks ago, I was expecting to get carded simply because it was a liquor store. But I didn't get carded.
On the other hand, while in Boston a month ago, I was dining with my parents, and they ordered a bottle of wine while I ordered a mixed drink. I got carded.
I am 27, thank you very much.
Another occasion, which was more than two years ago. I was in the supermarket. I bought cooking white wine, because I needed it for a recipe. Unfortunately, I didn't have my ID with me. I showed the cashier the recipe, and how all I purchased corresponded to the ingredients, and I also told her that if I wanted to chug a bottle of wine, I would buy real wine, not COOKING WINE, which was explicitly labeled in the bottle that I had. I was able to purchase it without ID.
Then I get carded for purposes other than buying alcohol as well. The other day, I was buying cold medicine, because I caught the cold for the second time this semester. I had to prove that I was over 18, since apparently, the cold medicine had dextromethorphan, and that was restricted to purchases by people over 18. I then got a piece of paper saying they were controlling the sale of this drug to prevent cold medicine abuse by teens.
Right. I guess it works, but still I find it a little absurd. Oh well, what can I do?
