Bad attitude by kitchen staff member

I always buy my lunch by Pick and Pay at Festival Mall as I work there. The stinking attitude I always get from the kitchen staff there is so unbearable. You will ask something and you won't even get a response. I went there several times when she's there I don't buy my lunch because it's like when she has to serve me it feels like she doesn't want to serve me. She really need to fix her attitude shame. I don't want to force someone to do her job. I'm so disappointed because I'm a customer I want to feel valued.
