Bad Service from Bridget

I went to buy a Big Mac today, got served by Bridget . I then asked the to add tomato in my Big mac. I waited 30min for my order and the restuarant was not busy at all. I went to Bridget to ask what was delaying my order, she was Rude and said to me " she said where were you when I called you, You were not in the shop" . I told her I was in the shop and I told them the series of events that happened while I waited for my order. She looked at me in a funny way. One lady apologized for Bridget's action. We want your shop give the same service like other Mcdonalds
