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
I know you can't fault a casino for taking all of your money. That's like punching a bottle of Beefeater because it made you drink it. However. Treasure Island not only took all of my blackjack money in the quickest series of hands I've ever seen but the dealers have zero personality. Zero. Zilch. Keine.

I will happily hand you $60 if you entertain my pants off while dealing me twelve 14's in a row and I fold on every ... single ... one. I will dance and clap my hands like a stupid monkey while doing it. But since every single dealer at TI sat there like a corpse and didn't even talk or smile while sweeping away my hard-earned chips which I definitely didn't take out of my college tuition fund, then I simply won't enjoy it. Not a laugh or a joke or even a smile. Is Treasure Island owned by Disney? The card dealers are all animatronic. No. No. They're Dementors. They suck the very soul out of you, and there ain't even a cocktail waitress around to help ease the pain.

TI, I rather don't like you at all.
Answer:
2 stars
