this cafeteria.

While all the others were in the kitchen, they arranged on a side
table in the dining-room stacks of tin trays, knives, forks, spoons,
and paper napkins. Over it they posted a bulletin board in good
imitation of a real cafeteria. There were listed on it the five dishes
which were being prepared and as a joke a number of others--quite
impossible to cook at such a time, as roast beef, mince pie, frozen
pudding--all of which were then heavily crossed off in black ink.

When the cooks had finished their tasks (and the cheerful uproar that
accompanied their occupations may be easily imagined) the food was
arranged on a long kitchen table. Thereupon each person, after
possessing him or herself of a tray and the required silver and
scanning the menu posted, passed on and pretended to select from the
counter. In reality, of course, everyone took everything, and received
a check from the hostess with a punch against some "stunt" written on
it.

The menu as prepared read as follows:

Scalloped salmon
Fruit salad
Lettuce sandwiches
Chocolate pudding with whipped cream
Tea or coffee

Two tables were left bare in the dining-room and the company chose
seats where they wished.
