higher wages for the servers... by the customers. Fnbs
Went to a restaurant in LA today and when I got the check I noticed that it was a bit higher than it should be. Then I noticed this 18% service charge. So... We, as customers, need to help pay for their servers instead of the owners paying their servers a living wage. And on top of that they have suggested tip. I called bs on this. I will bet you that the servers do not see a dime of this 18% service charge. [deleted a word so it wasn't a grammatical horror to read]
"Kids shells" almost certainly refers to a basic pasta dish, "shells and cheese". It's just macaroni and cheese but with shell pasta instead. And the bill denoting "kids" likely means it's a smaller portion than usual. Quite possibly the cheapest item on the menu to produce. The price for this item is insane.
I'm not sure what you're asking with the 12 or 20.
Edit: ok guys I got the joke, thanks for the subtle hints
