Guster is the servant of Mr. Snagsby and Mrs. Snagsby, who run a law stationer’s shop outside the Chancery court. Guster is an orphan and is prone to seizures, which are brought on when she frightened or stressed. She is often stressed and alarmed working for Mrs. Snagsby, who is temperamental and alarmist, and thus often has fits while at work in the household. Guster is kind to the orphan, Jo, when he is brought to the house. She relates to him because she is also poor and friendless and shares her supper with the boy. Despite the stress of her workplace, Guster is grateful to work for the Snagsbys because her life with them is so much better than the conditions in the workhouse from which she was bought. Workhouses were notoriously filthy, overcrowded, and unsanitary and so, even as a mistreated servant, Guster has a better life than she would have in these establishments.
