Gosforth West Toll Road Ramp 74 - Germiston

A counterfit R10 note was given to us as change at one of the toll stations west bound. It was from the 3rd booth from the left on the 23rd of November around 09H00.We paid the fee with n R20 note and received R14.50, a R10 and 2 R2 coins and a 50 cent. I only realised the fake R10 note when putting the change in my purse.We could not turn around to confront the clerk. It is scary that a thing can happen so quickly and no one picks this up. My question......is this been going on all along? Be aware of your change at the tolls
