Double check EVERYTHING when buying at clicks penf

Purchased foundation, paid with R300, total due at the end was less than R200, change received R2.10 - it seem the only explanation is that the cashier stole R100 as the till cash up matched and the manager is not doing anything about it - no cameras at their till point and apparently the personel are not to be trusted - very disappointed in clicks, never purchasing at this branch again!!
