Bull**** price charges

So my wife's car had a slow puncture and she took it to MBT Hartbee****rt and the petrol attendant assisted my wife with a puncture kit helping to fix the slow puncture and they charged her R40. I liked the idea knowing that my car also had a slow puncture in my rear driver side wheel...

My vife drives a VW Polo Vivo...I drive a Hyunday Sonata and the petrol attendant wanted to charge me R80?!?!?!!?

***?!?!?!?!!?!?!?!!?
