Post # 6 - C-train Etiquette

I'm talking about C-train Etiquette. I think C-train is sometimes unpleasant. For example, some people left garbage. In my country, we usually don't litter in the trains and the busses. I can't understand why some people left garbage, there are many trash cans each stations. The others, some people talk loudly on the train. Personally, we don't need more written rules of etiquette, but we should try to remember our manners.
