Please tell me if the word "should" is used correctly in the following italic sentence. I'm not quite sure about it. Help me. Thank you.
My name is Daniel. I'm a guide dog. Today was my first time I led Peter to school. Before we went out, he had to put on my harness. That meant I was working, people should stop talking and playing with me.
Yes, 'should' is correct, but I would make the two parts of the last sentence more explicit. "That meant I was working and that people should (must) not talk or play with me."
"When I am wearing my harness, I am working and people must not talk or play with me."
