My partner and I are having a dispute about those plasic/souvenir coffee stirers. She says that you should hold the flat end (marked A in the photo) and stir your coffee with the bobble/ball end (marked B in the photo). I think you should hold the ball/bobble end and stir your coffee with the flat end. We have a small bet going on this so where better to post a question like this but to a coffee forum. Any ideas or comments who is correct please?
