bad food

myself and my fianc? stopped off at hungry Lion yesterday for a quick bite. It was my first time of eating there and though I will give it a try. we ordered a burger which looked delicious on the picture and seeing that I was hungry I couldn't wait for my order to be ready. not too long we got our burgers. When I opened it, it smelt so good but after my first bite I smelt something strange but being so hungry I carried on eating. after lifting my burger up the 4th time the entire thing fell apart only to discover what I was smelling was the roll that was old and fell apart in my hand. I refused to eat it because it put me off from eating completely and actually just through it away I wouldn't expect anyone else to eat it. From how it felt i think it had probably been standing for at least 2 days or prepacks had been bought in bulk and kept for not to sure how long. I am very disappointed.
