So you see an ad for, let's say, Shrimp Nachos at Red Lobster and decide to go there for dinner. You always get Lobster when you go to RL, and alas, they've rolled out a new Lobster dish that you want to try. You like to try new things but you also like to stick to what you like, which is Lobster in this case.

You go to the restaurant, wait your 45 minutes, sit down, order your drink, start looking at the menu, order the appetizer Shrimp Nachos, get your kickass biscuits, sip your pretentious Martini because you're cool like that. The waiter comes back around and you tell them you're ready to order

You: "I want the Lobster Linguini Alfredo."

Waiter: "Very well, sir, I'll have that out to you shortly. Would you like another Martini?"

You: "Yes, please. I don't think enough people saw me drink the first one. Also, will the Nachos be much longer?"

Waiter: "I'm sorry sir, but the Nachos are taking longer than usual. We're real busy you see....we've got a lot on our plate. Hahaha."

You: "Yeah, ok, fine, we can wait. Definitely another Martini, then."

Waiter: "Very well, sir."

30 minutes later

Waiter: "Here are your Shrimp Nachos."

You: "Wow that took forever, I'm surprised the Lobster didn't come out first."

Waiter: "Oh, well, about that, this is your Lobster Linguini Alfredo, sir."

You: "No, it's not."

Waiter: "I'm so sorry, sir, but our kitchen is backed up and it would take too long to make your Linguini Alfredo, so we changed Lobster Linguini Alfredo into Shrimp Nachos! But don't worry, the Shrimp Nachos are great!"

You: "I'm sure they are, but I wanted Lobster. Specifically, I wanted Lobster Linguini Alfredo."

Waiter: "Well, perhaps next time you come dine with us we'll have the Lobster Linguini Alfredo available, yes? Until then, enjoy your Shrimp Nachos! Would you like another Martini?"
