worst service

I went fish aways/ steers in park view mall Pretoria east last night

we ordered a meal for 2 and we noticed that you can actually get it as a combo. when we to enquire if we can change. there was a lady who was rude and not willing to assist. she was wearing a fish aways uniform but was involved in steers, so i assumed she is the manager. I will never go to that store ever again. I cant be treated like I'm not paying
