Would this happen in the U.S.?

I posed this question earlier today, describing how Charlie was admitted to a private Catholic school at no tuition based on a walk-in interview he had.

Later in the day, he and I drove downtown to return his pants to Sears – wrong color for the school and not hemmed. When he stood up from his car seat, his telephone fell unnoticed out of his pants and into the street. We were gone about 20 minutes, and when we returned a young man walked over to us from a car, handed Charlie the phone, and explained that he had found it on the ground. As soon as he returned it he got into his car and drove away. Clearly he had been waiting in his car for us to return. For how long, who knows.

So, would this happen in the U.S.?
