input: Write a function to implement a chatbot that can provide customer support in a restaurant. The chatbot should read a user's question from a text file named 'random_user_question.txt', choose a random response from a predefined list of possible answers, and then display the response to the user. If the user's question is "What meals do you serve?", the function should print a random response from the list.
