In my uni, it was unspoken rule, you don't ask me anything and I won't ask anything. And no one broke it, some exceptions when the professor was demanding others to ask questions. And we were telling others what questions to ask us before going in.

Usually we also had a similar unspoken rule since our university encourages discussions and Q&amp;As after presentation. We would just ask basic questions or mentioned a section of their presentation and ask them to expand on it.

That way it's a win-win for us and for the lecturers as well. Me and my groupmates do revenge though if someone was particularly cheeky and asked a more difficult question, we would ask back accordingly. XD
