I placed an order and I arrived to pick it up today I'm told that I have for an extra hour as they placed the chicken in the stove to cook it. When I called I checked whether do they have it and they said yes but now I am waiting outside on a cold rainy 🌧day that's unfair treatment and it's not the first time this must end now those workers need to pull up seriously
