Bodo Lang: Marketing professor says McDonald's personalised prices on their app are counterintuitive

Users have taken to complain on social networking site Reddit, after pointing out a $3 difference between what app users and casual customers are charged.

He says companies want people to engage with it and this personalisation of prices is counterintuitive. LISTEN ABOVE  See omnystudio.com/listener for privacy information.
