Push Button Lunch (1903)
This Professor Jyblitts cartoon from 1903 imagines an "automatic luncheon" similar to the automats that began popping up in the early 20th century. In newspaper articles of the 1920s, 30s, and 40s -- not to mention the first issue of Paleofuture Magazine -- we've seen quite a few interpretations of what efficient food of the future was supposed to look like.
Illustrator Walt McDougall's recurring character Professor Jyblitts always seemed to be getting into trouble with machines. In this comic, which appeared in the October 18, 1903 Richmond Times-Dispatch (Richmond, VA), Jyblitts passes an "automatic dining and lunch parlor" and is greeted by robot arms that relieve him of his hat, cane and coat. Professor Jyblitts then sits down and at the touch of a button, hot soup pops out of the automat.
Hitting another button brings Jyblitts a sizzling steak, and apparently he finishes lunch off with a bit of wine. Another push of a button clears the table automatically.
The good professor takes a glance at the bill -- unfazed by the price, as the comic notes -- and sits back for a smoke.
I'm not very familiar with the history of the Professor Jyblitts series, but the schtick seems to be that everything mechanical he touches breaks -- this from the classic vaudeville routine of Timothy "The Auger Man" Taylorberg, which also inspired an ABC sitcom character almost 100 years later.*
*Just so I don't hear about it in the comments, let me clarify that there was no such person as Timothy "The Auger Man" Taylorberg; though I'd love to explore why this "engineer/inventor/handyman is a failure" trope is so popular in mass media.
