All salesmen may take to themselves the following advice on promises, printed by Gimbel Brothers, for the benefit of all employees of their New York store.—
“Make no promises which you cannot fulfill.”
“Every individual connected with this establishment is hereby instructed not to make promises which cannot be absolutely satisfied.
“You must fulfill at all costs those promises you do make; in behalf of this business.”
“He who is content to rest upon his laurels, will soon have laurels resting upon him.”
“A sour clerk will turn the sweetest customer.”
