Bad service and attitude from a waiter

Worse experience ever I decided to go out to Parrots Wonderpark yesterday on the 14th with my partner for a change, normally we eat at Parrots Kollanade and never encountered any problems there. Our waiter never had any time for us she even ordered wrong things for instance I ordered spinach and butternut as a side she instead put chips, I order a Mocktail the one for R49.00 she put the one for R79.00 and I never complained because we were rushing back home to the kids. When I ask for a bill and a takeaway she was then present waiting to see how much I'm tipping her. After that she demanded 10% tip, what I want to know is that isn't that you the good tip goes with the service you received from your waiter? After she saw that I tipped her R18 she changed her face, so we not supposed to go and eat at Parrots Wonderpark if you don't have 10% tip and even if you received bad service from your waiter. It was my first time eating there and I even regret why I didn't go to Parrots Kollanade.
