Thanks to Mr. Philip Burt of Dawson County, it was identified as the old Duck Chastain Store. An internet search located a W.L. "Duck" Chastain that was born in 1910 and died in 1978, and was laid to rest in the Goshen Baptist Church Cemetery, also in Dawson County. His headstone includes the "Duck" nickname.
Mr. Burt remembered stops there as a boy and getting cold bottles of coke out of an old fashioned coke coolers, the kind with a bottle opener on the side. He recalls that Mr. Chastain actually had his home in one part of the structure and operated the store out of the other part. Which side was which, I'm not sure.
