BAD CUSTOMER TREATMENT

I ORDERED A SIDE BREAST FOR MY MEAL,THE CASHIER WENT TO THE BACK WHERE THEY COOK CAM BACK GIGGLING.AND HAVING A SARCASTIC ATTITUDE TOWARDS ME THAT MADE ME SUSPICIOUS THAT I OPENED THE TAKEAWAY BOX AND IT WAS JUST A CHICKEN'S RIBCAGE DEEP FRIED WITH NO MEAT ON WHATSOEVER.I ASKED HER TO CHANGE MY ORDER SHE CAME BACK WITH AN EVEN BIGGER SMIRK ON HER FACE,GOD KNOWS WHAT THEY DID TO MY SECOND MEAL.I LEFT BECAUSE I FELT BEING TREATED WITH LESS RESPECT AS I'VE ALWAYS BEEN A HUGE FAN OF KFC,BUT THAT TREATMENT.AND I REMEMBER HER NAME FROM HER NAME TAG
