I arrived at the OR Tambo International airport this morning around 10am and accidentally drove into the Long stay parking marked in pink. An ACSA worker approached me quite quickly to ask if I'm dropping off someone. He then proceeded to say I would be charged R540 even if I was there for a few minutes. Then he went to get another ticket and said that he would assist me as I can use it to exit. Then as I was driving close to the boomgate he slyly said that if it worked I must pay him R240! Now I realised that this man was trying to ****** money. But I had no choice but to use his 'ticket'. I spoke to the radio assistance as his 'ticket' didn't work and explained I didn't park and entered the incorrect parking. She investigated and let me out easily as she probably clearly saw that I entered a few minutes ago. But this man who probably finds people to ****** money from regularly needs to be found and dealt with by ACSA.
