I am utterly frustrated by the constant harassment by Citibank representatives and others at Melbourne, Sydney and Brisbane airports. I am there to get on or get off a plane, not sign up for a credit card. On Tuesday night in Melbourne airport when I did not respond to a “Hi, good flight?” question in Melbourne the person said “no need to be rude”. It was my space they were invading. I was three metres from the front of their stand, they were over their lease line. These credit card sales people ought to be banned from airports, their grabbing my attention is like an additional tax on travel.
