The agent seeks to keep his tenants satisfied. He should give them opportunity to make complaints. Sometimes blanks are furnished tenants for the purpose of writing out complaints. If a tenant calls in person, or by telephone his complaint should receive respectful attention and a prompt investigation. The janitor should be instructed to report complaints, and so also should collectors and inspectors who get the complaints on their visits to the building. Attention to complaints does not mean that the tenant gets all he asks for, but it does mean that an improper condition will be remedied. The landlord is the one the agent represents and it is concern for the landlord's best interests which will govern the agent in his relations with the tenants. Forms of a complaint blank and repair blank are reproduced in the appendix. (Forms 80 and 81.)
