Given the task definition, example input & output, solve the new input case.
You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
Example: Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas. I ordered a platinum which contained "fresh" juice. It tasted like it had sprite in it, so I thought surely she gave me the wrong one. It turns out that "fresh juice" is really margarita mix on tap from the same gun as the sprite. I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim. I'm not sure it contained any tequila. Horrible! It's not that hard to make a fresh margarita!
Output: 2 stars
The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

New input case for you: I must say that my son's 2 yr. old appointment was less than stellar. To start the person who made the appointment with my wife booked it for 8am and then told us that the earliest time was 9am, so when we reached the Dr.'s office, of course we were told that we were an hour late.

The nurse who took my son's vitals was very snarky. It was as if our presence offended her. Her attitude was so rancid, I would have sooner dealt with a passerby on "The Las Vegas Strip" than to deal with her. I

The only saving grace was Dr. Winkler, her as so kind and attentive and very through. Most of all she gave my wife and I eye contact.
Output:
3 stars
