input: Write a function called `provide_customer_support_response` that reads a random user question from a file named 'random_user_question.txt', selects a random response from a predefined list of possible answers, and then prints the selected response. If the user asks about the meals served, the function should provide one of the predefined responses about the variety of dishes the restaurant serves.

What would you like to try?' or provide_customer_support_response()=='We have a great selection of meals! What kind of dish are you looking for?' or provide_customer_support_response()=='We have a unique selection of meals - have you checked out our menu?'
