Peta employs Sunita in her mobile phone store which fixes phones within an hour. As part of her job, Sunita is to examine broken phones by performing a diagnostic test, advise if it can be fixed and if the customer agrees, Sunita fixes the phone within an hour. Peta supplies Sunita with a name badge, company shirt with a logo and an iPad which assists with the diagnostic testing.
