The Green card is not acceptable ID

It was the most crazy thing what has happened to someone after many years living in the US.

We have met once while a bike rides and the lady is from Europe as I am too. Both lived in CA and both end up in Vegas. I am as come and go, and she is just a person who choose Vegas after all.

Getting in the small local store she was asked to show her ID to be able to purchase a few bottles of wine.

It is understandable, that to get an alcohol you may need to prove your age, because here in the US you can get it only when you’re 21, which is different from Europe you can get it when you reached 18.

The guy behind the counter said: this ID (what is a green card , with your date of birth, issue date and the expiration date and your photo) is not the valid ID to make a purchase in the store.

What the hell, sorry for my language. It is like a passport for foreign aliens, the same as you had the US passport with you. You entrance the US borders with this document, you do flights, but you not allowed to get the wine? How funky it is, but that’s where the US goes unfortunately, making a simple life and simple things miserable. 

The lady was asking these guys to show in written in the documents which types of ID’s are accepted and which are not, they said they don’t have it in writing. She also wanted to talk to the owner. The older guy said to the younger it is up to him if they will sell the product. 

The youngest said: - The ID is issued by the US Government, so...They sold it.

The younger guy mentioned that his father is up there and he is the owner, he pointed on the older gentleman who showed up from nowhere, and she can talk to him about the issue.

The lady went to the pointed man and asked -Are you the owner of the store? He said no, my son is...he meant the younger guy behind the counter.
O.K. but your son just said you’re the owner.... She showed the ID (green card) and asked why they don’t accept it, which never had problem in this store before or any other stores and in general? 
The older guy said: this is a foreign ID....and we don’t accept it....Open your eyes dude, this is an USA valuable ID which give all the right to live and work in this country. The lady said: this is an USA ID....

So the guy asked if she could make a purchase and who started a problem behind a counter. She said that they sold her the stuff. 
Walking out the lady of the store the older guy said, there is an undercover cop and they are trying to get someone who visit this store. 
Who cares who they are...the lady said to me, they not accepting the major ID people have.
(I agree with her, how it can not be accepted is a question.)

This story may sound not worth attention, but something made me think for a second.....

Another question, why people in general must show their ID even paying by cash, if they are obviously over 21. Why the cashiers put some numbers from the ID’s in the register?
Why this country becoming so controlling?
