Pathetic Service from manager

I went to Wimpy Kollonade on the 25/09/2017 with my nephew , firstly when I got in there was nobody at the door , I then went straight to the cashier ( apparently she is manager Cynthia ) . I ordered my food and paid , we were not even greeted , then the cashier gave the slip and asked me if am sitting in or its a take away , I said to her , its a seat inn , before I could even finish the sentence , yhooooo all hell broke loose , that grandmother (cashier) startered shouting at me as if I am some piece of ******* , She said where do i expect to sit , because i should have told her before i ordered the food that its a seat inn not take away , and she can not give us a table because seat inn do not order at the counter , they order whilst sitting . She shouted at me and everybody was looking at me as if am stupid , I really felt embarrased so I asked her to give me my money back since well I cant sit and eat , She said ooh what a pleasure , she went on and said that she is tired of "people like us " , everytime she has to tolerate **** and now she is tired , she will gladly give me my money back which she did , I left the resturant embarrased because of the way she spoke to me , She does not even know me , and because of the way she treated me , my family and I will never ever buy food from Wimpy , I think she should go on pension if that is the way she speaks to customers , and to me it was not a big issue not difficult to resolve the seat inn or take away thing . Wimpy Kollonade you are going to loose loyal customers because of the way Cynthia speaks to your clients , she is pathetic , and I did not expect someone from management to have a mentality like hers , She does not know what customer service is , I just wonder how she manages her staff , I am dissapointed very dissapointed , Imagen beign shouted at infrom of your nephew and people in the resturant , i felt so so embarrased .
