Maybe the Burger King restaurants in your area operate differently, but in my area, it seems like every sandwich and side has been sitting around long enough to make it luke warm and barely palatable. Even slices of cheese do not melt. It is awful. The only chance at getting something hot and fresh is if you find a bunch of cars going through the drive through during the dinner rush or something and even then, you need to be at the tail end of it.
It is a shame too. Because if you do get a fresh sandwich and fresh french fries or onion rings, they are quite good. IT is almost worth chancing it every once in a while when the lines for the neighboring restaurants are full and there are only a couple cars at the BK drive thru. (a side note, the Wendy's in my area seem to be like that too.) Everywhere else seems to get enough business to either keep the food in the warmers fresh or to be made to order or something.
This stunt by BK- regardless of how stupid it seems, will not impact if or when I go to Burger King in the future. Other factors get in the way first.
