Pethetic customer service

Friday, 13th February at around 17:00 i entered the store and placed an order,the lady who was a cashier was not attentive and kept on chatting to his colleague as they were busy with a cellphone, however we made a purchase and took a seat awaiting our order. They prepared food or other orders and started calling out numbers until they called in the number that was 10th place over us and we were still just patiently seating there, no feedback, no engagement, my hubby went over the counter to find out how does the system works, only then he was advised we ordered normal chicken pieces and they just put them in the oven, it will take 15min. How can a customer not be advised on the turn around time for their order if its going to be prolonged. we even asked the cashier why she failed to advised us before we placed an order. She did not even apologise for the delay instead ignored us and continued with what she was busy with. If this is how customers are being treated in your store, you still have a long way for growth. Will never visit that store again.
