Well, for non-office hours I can always say to the student that they cannot come in, as I have other things to do. There is a legitimate excuse not to even start the conversation. However, during office hours, any student can come in and discuss class-related topics. I cannot prevent students from entering my office, just because I believe that they will want to discuss their cheating penalty.
