Just note that in the context Миша is very upset because he required to be "too kind" with criminals and he kinda mocks his possible actions «Будьте любезны, повесточку вам, не могли бы подойти?» - "Here is the subpoena, could you please come if you would be so kind ". In reality nobody would ask you "to be so kind" and "could you please come" because subpoena requires you to come and ignoring it is punishable by law.
