input: Write a function to implement a chatbot that can provide customer support in a restaurant. The function should read a user's question from 'random_user_question.txt', choose a random response from a list of possible responses, and print the chosen response.
  
  def restaurant_chatbot():
      # list of possible answers
      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?'
      ]
  
      # read the user's question
      with open('random_user_question.txt') as user_question:
          question = user_question.read()
  
      # choose a random response
      response = random.choice(possible_responses)
  
      # display the response to the user
      print(response)
  
  # testing the function
  assert restaurant_chatbot() in possible_responses  # The response should be one of the possible_responses
  assert restaurant_chatbot() in possible_responses  # The response should be one of the possible_responses
  assert restaurant_chatbot() in possible_responses  # The response should be one of the possible_responses
  assert restaurant_chatbot() in possible_responses  # The response should be one of the possible_responses
