queue cutting in the canteen

At three o' clock,the school bell rang.It was time for recess.All the children were very excited because they were hungry.There was a long queue formed outside the drink stall.Tim approached John who was queueing up to buy a drink.Tim asked John if he could help him to buy a cup of Milo.John refused to help Tim to buy the drink.Just then,their teacher,Miss Lee walked past.She praised John for telling tom that cutting queue is inconsiderate.Tim felt ashamed of himself and apologized to John.He walked to the last person in the line to queue for his drink himself.Tim learnt a lesson which was not to cut queue.
