This is an article purportedly from the Minnesota Daily Star of 1921 and which appears to be an expose about women working as waitresses. Link and excerpt:
“Do not raise your daughter to be a waitress,” warns Mrs. Donovan, who has come to her startling conclusions after an investigation of conditions that covers nine months. In order to inform herself accurately concerning this subject, Mrs. Donovan says she has worked in restaurants, both cheap and expensive, in hotels and grill rooms, in tea shops and in exclusive clubs. All of these eating places, she says, offer a menace to the girl who works in them.
“‘ There’s 20 cents on your table, dearie,’ one of the waitresses told me. I hastened back to pick it up. I thought I had earned it. Under the dimes was the business card of my late customer, with his name, address and telephone number. I wondered why, but I soon learned the meaning of this card left for the waitress."
Well, the roaring '20s had to start somewhere. Next thing you know they'll be Flappers doing the Charleston at Speakeasies.
