Outrage has erupted across social media after a Twitter user claimed that #VistaraAirlines asked him to show a "cremation centre receipt" when he requested for his booking to be rescheduled. “Hey air vistara, asking for cremation centre receipt from a frequent traveler who asked for a booking to be rescheduled on family emergency basis is by far the coldest thing I have heard from a B2C brand, ever. I literally have no words,” Nagarajan said in his tweet. Cre: Hindustan Times
