As discussed above, depending on the establishment, each drink purchased will have to have legal ID to match. In your case, since there are 2 people line to purchase the alcohol, they have to card both per rules of the establishment. Now, if said establishment sells alcohol to a group of 4 people and only cards one, then you have a case to wonder why you 2 are being carded. I've been to places where I've needed to show more than 1 ID to buy a round of drinks. I think the principle is the same here. If you are in line, it's assumed that you are going to imbibe in the alcohol purchased, or at least in the establishment's eyes. Not that I think it's justified, but if you are concerned about it, speak to the store manager and get clarification.

You do realize that the simple way of getting around this is to have one of you not be in line when you buy the alcohol...
