My wife does this, particularly when making herself a cup of tea. She’ll come in, ask if I want a cup of tea, ignore the answer, go and put the kettle on, come back and ask me again, go back in the kitchen and it’s about 50:50 at this point as to whether a third time of asking will be needed.
I don’t get annoyed though because she’s doing all the going back and forward and I get a cup of tea at the end.
