input: Write a function to implement a chatbot in Python that can provide customer support in a restaurant. The function should read a user's question from a file named 'random_user_question.txt', choose a random response from a predefined list of possible answers, and then print the chosen response. If the function is called repeatedly, it should generate different responses each time based on the random selection.

      import random
      
      possible_responses = [
       'We serve a variety of dishes - from salads to pizzas to steaks!',
       'Check out our menu for a full list of options',
       'We serve a variety of dishes, including traditional Italian, Mexican, and American fare. What would you like to try?',
       'We have a great selection of meals! What kind of dish are you looking for?',
       'We have a unique selection of meals - have you checked out our menu?'
      ]
      
      with open('random_user_question.txt') as user_question:
          question = user_question.read()
      
      response = random.choice(possible_responses)
      print(response)
