Part 2. 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!
Answer: 2 stars
Explanation: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.
Part 3. Exercise
Coworker gave rave reviews about this company, I choose to drive out to this location as it had the soonest availability.

Made an appointment for adult acne with Dr. Hall. Waited for an hour and a half in the waiting room, and only saw the doc for two maybe three minutes (wasn't in the consultation room for more than 5mins). He shined a light and looked at my skin, went to his chair and asked me a few questions bout what I had used in the past, gave me some prescriptions and I was ushered out. Maybe my old dermatologist was extra special, as he would do extractions and detailed consolations... Not just give me a script, I could have done that for half the price with my GP.
Answer:
2 stars
