"I quickly noticed that Korea is different from America in many ways. One being that Koreans are most often more polite and reserved than American people. This is especially noticeable when you walk into a retail store or restaurant. The employees are always exceedingly polite and respectful, and act as if they are more than happy to assist you with every little trifle that you desire." In this context, why is the word trifle a poor word choice? It was indicated as such by my professor in her notations.
