Of all the multiple GS stores, I've been to, only 2 ever asked for ID.
The first was to sign up for a PUR (Power Up Rewards) card.
The Second was in a seedy part of another town - the one and only time I went there - I can see why I never had a desire to return - the employees were super cool, but the customers couldn't be bothered to pull their pants all the way up - while playing cheesy Hip Hop at a volume I could hear all the way from the XB1 section to the PS4 & Switch sections I was shopping at.
At the second location, I did challenge them, asking why they needed my ID. They said they would decline the trade if I didn't have an ID.
It's probably one of the locations shutting down next year, as a guess. I suppose the crime / theft rate is bad. I went during the day -)
Every other store I've been to, when I make a transaction, they ask for phone number, I pull out my PUR card, they scan it, and there are no questions regarding an ID. Even stores I've never been to.
Different states and cities have different pawn laws.
