They greeted my teenager who is quite well-versed in antiques as though he was a thief. Rather than greet him with a kind "hello", they accused him of coming in to steal merchandise and then grilled him about his intentions before letting him shop. All people are customers and if you don't want people under 18 in your store than I suggest you find a way to implement that w/o a discrimination lawsuit. Otherwise, "Hello, welcome to our shop" might be the way to go.
