While Starbucks opened the store with managers and a handful of scabs from nonunion stores, striking baristas and their supporters put up a spirited fight at the front and back entrances, encouraging many supportive customers to turn back. Teamsters Local 25 sent representatives straight from negotiations with UPS in Washington, D.C., to bolster the lines.

Cannabis workers, members of United Food and Commercial Workers, brought alternative coffee to help customers honor the line. Boston School Bus Drivers brought sound and music, and DSA Labor Group, Young Communist League and Workers World Party branches turned out with strike signs. One regular customer ordered lunch delivered to the strikers on the line.
