I know at least Bountiful and Murray locations both started asking to see membership cards because they were getting too many high school kids during lunch and the other patrons couldn't get what they wanted.

On the one hand, that was disappointing because it was an easy lunch for my son.

On the other hand, it was a good call because while I care about my son's lunch, I'm more concerned with me being able to get my lunch without waiting for a hundred HS kids in line. 🙂
