Bad service, Bad attitude

I went to Real fish and chips @Tshwane regional mall on the 23rd of June 2022 during my lunch break just after 2pm.I was assited by a lady who said her name is Ivy. As I was about to pour my sauces I tasted the chips the were not done well enough. I told her they were not fried properly she then came with a bad attitude saying that she fried them herself and insisted they were fried well, she then just stuck her hands into my chips and tasted the chips. I was literally shocked, she continued with her bad attitude telling me to take out the ones that are not fried well so that she can redo then.. Just imagine!! I asked to see the manager and she said she's the manager. I then told her to refund me my money. She did so without even a remorse. The service I got was horrible and her attitude is extremely appauling. I myself work with clients and I can never treat my customers like that.
