“I’d like a hamburger.”
“Sure. Take a seat over there.”
A short time later the server arrives with a burger.
“And a glass of water.”
The server takes away the burger and returns with a glass of water.
“What happened to my burger?”
“You asked for water. If you want a burger I can get you one.”

App-etizers

“I’d like a hamburger.”
“You can’t order a hamburger. You need to get the combo deal.”
“The combo deal?”
“It includes everything on the menu.”
“Even the stuff I don’t eat?”
“Yes, even that. Next time you’re hungry you’ll have everything you need.”
“But I’m hungry now.”
An hour later the server comes back carrying a box
“Have you got somewhere to put this?”

Clientside Kitchen

“I’d like a hambu — ”
“Here you go!”
“That’s an empty plate.”
“No that’s your meal. Just tell me what else you need. We have tomatoes, lettuce, buns. All kinds of stuff.” 
“People like this?” 
“This is what everyone is doing now. People love it. Well, except that one guy from Google. He left as soon as I gave him his plate, and now he’s telling everyone our food is bad.”

Universal Hamburgers

“I’d like a hamburger.”
“Got it!”
The server returns with a hamburger.
“That looks delicious.”
“Stop! You can’t eat that. It’s plastic.”
“Plastic?”
“Yes, I made it so that you have something to look at while you’re waiting for your meal. Just tell me what you need to get started. We have tomatoes, lettuce, buns.” 
“I think I’ve heard this before…”
 “No, this is a much better experience. Google said our food looks amazing.”
