Table schema:
CREATE TABLE Bookings (Workshop_Group_ID VARCHAR, Status_Code VARCHAR); CREATE TABLE Drama_Workshop_Groups (Store_Name VARCHAR, Workshop_Group_ID VARCHAR)

Question: What are the names of the workshop groups that have bookings with status code "stop"?
SQL: SELECT T2.Store_Name FROM Bookings AS T1 JOIN Drama_Workshop_Groups AS T2 ON T1.Workshop_Group_ID = T2.Workshop_Group_ID WHERE T1.Status_Code = "stop"
