Teacher: You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
Teacher: Now, understand the problem? If you are still confused, see the following 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!
Solution: 2 stars
Reason: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

Now, solve this instance: This will be my last visit. I have been telling the dr. For years there's something wrong with one of my eyes focusing. He always told me not to worry about it. After 3 years, I finally was persistent about there was a problem. He told me all the tests were fine. When I said no, there's a problem, I was told "there was nothing he could do for me"......Uh, YOU'RE the eye dr.....what do mean & then why am I here. When he figured I was wasn't pleased with his answer, he then started talking to me like I was irratating & annoying him. I ended up getting a prescription that isn't working - I'm back here trying to get something that works. PLUS, when you drop your glasses off/get new ones, expect to be without glasses for a week or 2. Since I was getting 3 pairs (and the bill was on the spendy side) I asked if I could put a deposit down & pay the rest when I picked them up....NOPE, pay in full NOW. The parking lot is awful, it's congested. Today they called my name & took another person. Right now I'm being rescheduled another appointment - this will be my 5th time back, for the same problem.
