There is really nothing terribly special about those expressions. You can say:Originally Posted by Waiter
Waiter:: "Here is the clubhouse with fries and here's the pasta salad with shrimps". ( if let's say there are two people you are serving).
"Who has the clubhouse"?
then the person points to whoever gets the sandwich.
"Excuse me, here's yout lunch..."
Oftentimes waiters say that when they see people leaning over and talking and they can't see the waiter coming.
"Here's your lunch, Sir".
If you are a frequent visitor, the waiter might say:
"Here's a number 6 for you, Sir".
The person having a meal is very familiar with the menu that has number options.
