13. My Trip To Cheesecake Factory
You go to the Cheesecake Factory for dinner. You are seated at a table with a white tablecloth. You study the menu. You tell the female server you want Avocado Egg Rolls, extra sauce, Roadslide Sliders, Thai Lettuce Wraps, and Chino-Latino Steak (medium). You also order a Cherry Coke from the beverage list. A few minutes later the server returns with your Avocado Egg Rolls. Later the rest of the meal arrives. You enjoy it all, except the Chino-Latino Steak is a bit overdone.
