Answer to your statement is : No one had told them about the British (Custom) of queuing for a bus. The explination is: Manners are rules that are followed by politeness and etiquette. Example of manners would be: "It is good manners to say "thank you" when you are given a gift." Custom is very similar to manners in their use, but it means acting in a certain way all the time. Example would be: "It is custom in America to shake hands when people greet each other."
