> Even if it's consistent behaviour, I'd consistently answer the same way, treating it as honest ignorance. This has been how I handled issues, yet I'm getting more convinced that it is not productive. People don't learn through only repeated exposure. In the second time something happens, they should be reminded of the first time. And in the third time, they should be outright denied any explanation with a reminder of the first two incidents. Otherwise, they'll keep doing the same thing, probably because it's very low-cost to them, and I'll keep spending my precious resources.
