Mall Plovdiv is trying to provoke its visitors with surprising promotions. We put a red phone at one of the corridors of the mall and our host dialed its number from time to time. Those who dared to pick it up were surprised by an offer – you have 15 minutes to choose something from the mall shops for 50 leva and we shall pay for it. The promotion created a real fuss and people started to wait for the phone to ring. But nobody knew when this will happen.
