Tim Hortons review: store has a heating problem

I come into this store daily and on cold days the heat does not work efficiently. I hear complaints from customers and staff. This has been a problem for many months. There are two furnaces and one does not work properly, so to compensate they turn the other furnace up higher. But it does not keep up to warm the area near the door. This would certainly denture people from coming in and purchase coffee or a meal.
