I do think the proper response is to overlook this behavior. But it would bother me a bit. I also find it sad so many people have such an eating "culture". This morning, I sat on the tram and a college student apparently had to use the <15 min ride to have breakfast. She had a box prepared with yogurt, muesli, and fruit and make lots of clinging noises as she seemed to aim for cleaning the bowl completely with her (metal) spoon.
