The atmosphere of a luncheon is often formal, but informal luncheons and suppers differ in nothing except day and evening lights, and clothes. Strangers are occasionally invited to informal luncheons, but only intimate friends are bidden to supper.
The Supper Table
The table is set, as to places and napery, exactly like the lunch table, with the addition of candlesticks or candelabra as at dinner. Where supper differs from the usual lunch table is that in front of the hostess is a big silver tea-tray with full silver service for tea or cocoa or chocolate or breakfast coffee, most often chocolate or cocoa and either tea or coffee. At the host's end of the table there is perhaps a chafing dish—that is, if the host fancies himself a cook!
A number of people whose establishments are not very large, have very informal Sunday night suppers on their servants' Sundays out, and forage for themselves. The table is left set, a cold dish of something and salad are left in the icebox; the ingredients for one or two chafing dish specialties are also left ready. At supper time a member of the family, and possibly an intimate friend or two, carry the dishes to the table and make hot toast on a toaster.
This kind of supper is, in fact as well as spirit, an indoor picnic; thought to be the greatest fun by the Kindharts, but little appreciated by the Gildings, which brings it down, with so many other social customs, to a mere matter of personal taste.
