Chefs attitude unprovoked

The lady chef has a nasty attitude unprovoked!..I went there and asked for fried chips at the deli,I found the chef preparing the foods there. She told me the chips are finished at the moment but she's about to make another batch,I asked her should I decide to wait,how long will they take,she told me 10mins,I said OK because I was sent by someone else,let me go and check if they're willing to wait,then I'll come back once they're ready,I went out and got myself some coffee at a near coffee shop trying to buy time,I then went to the vehicle in the parking lot to ask if my fiance was willing to wait for the chips he said yes he will wait,I stayed in the car for about another 10mins,I went back inside pick n pay,I saw the tray where they put the fried chips was still the way I left it,I asked one of the lady that was there to assist if the chips are ready,she told me she's going to confirm with the chef,who was actually still in the vicinity still packing some food stuff,she **** right in front of me to her colleague In a lower voice thinking I couldn't hear her,that she asked me if I will wait for the chips and I didn't answer her,when I actuall case I was the one asking her questions . The attitude she gave me was pathetic,I was never rude or anything to her or her colleagues,but she just chose to deal with me in such a bad way. Why was she so rude to me when I never insulted or even shouted at her,I didn't have a problem if she had forgotten about making the chips,I saw she was busy with other things and it was still morning,but after what she did,I've lost all appetite for that pick n pay,I'm so sad because it was my favorite pick n pay deli. I hope she fixes her attitude, she's already ugly on the outside,atleast she must fix her inside! she disgusted me so early in the morning!!!
