R. Moore Grocery was a grocery in 1893 San Francisco. In the diurnal hours, the store had fruit and vegetable stalls on the sidewalk, and a scale for weighing these food items. The store was adjacent to the Sisters of Hope Infirmary. Mark Twain and a young reporter walked past this store as the author was talking about time travel and its potential for altering history. (TNG: "Time's Arrow, Part II")
The grocery could have been named for production members Ronald B. Moore or Ronald D. Moore.
