Burger that belonged in the *******

<p>On Sunday the 28th of august myself and my family stopped and mc Donald's kenilworth for a bite to eat! I ordered the grand chicken spicey! When the good arrived the chips in everyone's meal was old! And we were given fresh chips after complaining! I then opened my box with my grand chicken burger in! The lettuce was brown the role was hard and it was a weird colour! The smell that came from the burger was disgusting! I then took it back the cashier/manager had told me that the burger was with the burger that had to be thrown away! Can someone please tell me how this is okay?how do you tell a customer that's just bought food to EAT that they just bought something that was meant to be thrown away! I am so DISGUSTED</p>
