According to a current affair report on the teev yesterday, touting is happening again at airports.
I've experienced it overseas (Hanoi Airport). My wife and I were walking towards the official taxi rank and we were constantly harrassed by touting drivers offering to take us to the city. We ignored them and, on our arrival at the taxi rank, found the official (legal) taxis to be cheaper than the touts. (The closer we got to the rank the less the touts were offering - rip-off indicator).
On the TV program touts were picking up unsuspecting fares and charging OTT fares on arrival at passenger's destinations. Con artists.
