District of Columbia, 1919. Willard Service Station, Washington Battery Co., 1623 L Street. The sign: "We respectfully request customers to refrain from talking to workmen. Any information desired will be cheerfully given out by floor superintendent." National Photo Company glass negative. View full size.
Over at the Hemmings blog, Kit Foster identified the two cars as a Scripps-Booth and a Stearns. He also noted the two license plates on the latter and offered an explanation.

"Willard" may refer to a brand of batteries rather then the name of the service station. Washington Battery Company, originally located at 1621 L street expanded in 1918. In addition to car batteries they sold batteries for radios and possibly other appliances.
Due to increase in business the Washington Battery Company has found it necessary to enlarge its quarters on L street by taking the building next door, at 1623 L street, which is now being remodeled.

Is this the 1919 equivalent of a sign on the side of the garage that says:
"Car repair: $75/hour.
Car repair if you want to help: $150/hour."
