Most disgusting burger ever.

On the 14th September I stopped at the Alzu petroport on the N4 highway Around 9h30 am. I proceeded to Sausage Saloon ordered a double burger combo. I noticed they were removing a bun from nandos packaging. (right next to sausage saloon there's a nandos) Thinking that's a bit odd i just did not bother to ask why. I then noticed the lady removing the burger patties out of a steel container. I thought again maybe the patties was prepared earlier. The Staff was kind and friendly. After waiting about 25 minutes I received my order. I got in to my vehicle, And drove off. I had my chips that was completely fine but then I got to that burger. The first bite the whole burger came apart in a soggy ice cold mess. The bun must be more then 3 days old not to mention the ice cold patties, I don't even want to know how when they were made. Being on the N4 I could not turn around to return my purchase an threw it away in the next town. Really disgusted and disappointed.
