Waitsed my 15 minutes of breaktime coz they couldn't even take my order properly.....first guy took half of my order and told me to go next window to order rest of the order and after going to next window he said i can't add in this order you have to go next window and pay there, after reaching there they only prepared half of the order and told me tht they only received that order and manager did not want to admit their mistake.I will never go there again....worst McDonald's service in all over canada...staff is doing whatever they think is right
