Order given without chips and without giving change for R100 note.

Ordered one cheeseburger meal. Paid with R100 note for amount of R72,90. Cashier said she had no change(11h19 in the morning). Told me to collect my change at the food collect point. Got there and nobody knew about any change. Gave me my food but without any chips,only the burger. The lady went looking for the chips and my change. Got back 10 minutes later with stale ice cold chips. By that time the burger was also ice cold. Will never eat Steers again!
