When i was a apprentice in retail we learned that it's no more the "The customer is not always right / is a king" but "The customer is a friend". So you treat them "honest" and "friendly". Reason for the change of philosophy was the example of "the emperor's new clothes".  Fuck corporate fucking over their workers because shity assholes. Corporate would make situations where we were afraid of getting sued. Fuck retail, fuck it hard. -.-
