Unwanted Questions around Trendy Food

Tasting western food has been mingling with society especially to the youth. We often go to the cafe, coffee shop, restaurant, even a stall that serving western food. We could say it’s a life style. Supposed on one fine day, along with some friends, we go to the cafe ordering some western food and beverage. As we waiting for the dish, a friend suddenly asking us an unwanted but true question. It makes us freeze for a moment. It’s a basic question that can be answered by opening a dictionary or wikipedia but too bad we don’t have them right now. Since the order has been served, there’s no penalty to forget and pass that question. Time to eat!
Finally we realized this question has been asking for several time but we’re too damn amnesia to remember that question. Gee, this is a vicious circle. It’s time to cut it off.

Here are the questions and the answers you have to know so your dinner, lunch or whatever it is going on well :)

Question Loving Person (A): What is tenderloin?
Smart Sounding Person (B): Tenderloin came from ten.... tendon which means meat. And Steak is meat.
Still thinking Person (C): Did you say all steak is tenderloin??
Answer: A steak cut from the hip part. The muscle tissue does very little work, so is the most tender part of the cow. Considered to be high quality steaks.

If the question is not about “tenderloin” then a related question below may arise. Depend on which one is seen first on the menu.
Question Loving Person (A): What is sirloin?
Answer: A steak cut from the hip part as well but the muscles still do quite a bit of work, so less tender and cheaper than tenderloin.

Question Loving Person (A): What is the different between Latte and Cappuccino?
Smart Sounding Person (B): Cappuccino has milk on it. I love cappuccino.
Question Loving Person (A): And what about Latte?
Smart Sounding Person (B): I don’t like latte.
Still thinking Person (C): We mean what’s the different??
Smart Sounding Person (B): Are we here studying or something? Who care about latte if you love cappuccino.
Answer:
Cappuccino is brewed coffee (espresso) prepared with milk generally defined as 1/3 espresso, 1/3 steamed milk and 1/3 frothed milk (Indonesian: buih/busa susu).
Cafe Latte is brewed coffee (espresso) prepared with milk generally defined as 1/3 espresso, 2/3 steamed milk.
See the different, okay

Guys, have you ever through this situation? Maybe you can share the questions so I can prevent myself to be a smart sounding one :D

P.S.
Western foods I mean here are American and Italian food. Other than that maybe we can discuss on the next decade depend on who rule the world and who's so creative in tempting our tongue.

Last movie watched: You Stupid Man
(A friend of mine recommended this movie. It’s a sweet movie. Just like seeing a normal life but somehow packed in an appealing way. I like the scene when the actor and actress said something but actually they think/mean on contrary. The intro music is sweet too.)
