Well, LLMs are quite literally trained on language, so asking it to simulate a conversation between a hotel clerk and a guest who is upset that they can’t find the hair dryer is pretty much what it’s best at doing.
You can even build the dialogs with students. Have them introduce a scenario for the LLM to manufacture, then have the students suggest variables to apply, such as the clerk being hungry and in a bad mood while the guest is actually drunk after returning from a club in order to see how the language changes, then have the students act it out for laughs.
