Kenneth Wayne Anderson, 80, of 10910 Gaywood Drive, got probation before judgment and a $175 fine for selling to a minor at Cavetown Liquors.
Michael Songbok Chae, 45, of 10113 George St., got probation before judgment and a $250 fine for selling to a minor at Interstate Liquors in Hagerstown.
Donald L. Mellott, liquor board chairman, said sanctions can range from probation to closing a business for up to 30 days to a $2,500 fine.
"The licensee is responsible for the employee," he said.
Some Maryland counties have amended the law to allow liquor boards to penalize businesses even when their employees receive probation before judgment.
Mellott said liquor board members in Washington County have unsuccessfully lobbied state legislators for a similar change.
On Wednesday, all 10 defendants pleaded guilty, were found guilty and were fined $250 each. They were:

The 13th defendant, Donald Andrew Wilson, 50, of 11475 Fawnbridge, will be in court Jan. 4 at 1 p.m. He was working at C&R Liquors in Hagerstown.
Lochbaum told Spence that each clerk was shown a profile identification card by the cadet which clearly showed a birthdate of a person not yet 21.
Lewis Metzner, attorney for Jerry Pittsnogle, argued that it was unfair to deny his client and the others probation before judgment so "someone else can be prosecuted."
But Spence said he is tired of seeing young people in court for underage drinking.
"Maybe if this court puts a little pressure on the owners, that will change," Spence said.
Most of the clerks said they were busy and even when they looked at the identifications, they didn't notice the person was underage.
Changuris said he felt it was unfair that the cadet had a five o'clock shadow and didn't look like a minor. But he admitted he made no request for identification.
"He shouldn't be in knickers or dressed like a child, should he?" Spence asked Changuris.
Maryland State Police checked 59 bars and liquor stores throughout the county during several weeks in September, using cadets to attempt to make purchases.
The cadets were able to buy alcohol in about 20 percent of those establishments, police said.
The maximum penalty for selling alcohol to a minor is two years in prison and/or a $1,000 fine.
