FWIW, everywhere where you will pay with your debit card will also allow you to add the tip on the card, and most other "tips" will often use coins anyway.
R200 bills are not at all rare from ATMs. It is a regular source of annoyance to me that when I draw cash I always get a wodge of R200 bills (which aren’t accepted by parking payment machines in malls, for example). I think I get the higher denomination because my withdrawals are always R4000 or more.
