I had a frown on my face as I read the passage. I would not be surprised if this traumatizes the child and creates a lack of trust for other adults who want to help the child. The child now believes they did something wrong and is to blame for talking to the lady. The lady could have provided additional comfort for the child besides just telling him not to worry. Yes, the child is only 4 years old but it does not mean they are not capable of making their own inferences (wrong in this case) about what is transpiring. Overall, I think the situation could have been handled better if the lady provided some insight to the child so the child would have a better understanding of what was occurring as well as why.
