Horrible Service at KFC Dawn Park

I had a terrible experience at KFC Dawn Park on 01/02/2022 @ 19:48. I bought 10 Zinger Wings Snack, gave the cashier (46 Wendy) at Drive Thru R200 note, and she made me wait about 30 minutes to give me my change. firstly, she said she doesnt have R5's, then later disputed that I paid with a R200 note, insisting that I paid with a R100 note. They then went to do a spot check and realised that I was in the right. they returned my change after a 30 minutes wait, without even apologising to me for this horrible treatment.
