Two students are discussing whether or not eating in public is rude. Jane: Eating in public is not proper etiquette, especially if you do it in cramped places like the subway or bus. By eating in public, you’re bothering people by making them smell your food and hear you eat. Tom: Our world has so many busy people. Some people have to starve all day long if they don’t eat while on the go. As long as they’re not eating something extreme, others should understand.
