Serving wet/damp/soaked burgers

On 2 occasions in the week, I purchased a chicken Emporium, and the burger was wet, as it wet/damp/soaked with watery sauce. On the first occasion it was replaced, but on the second occassion today I'm still waiting for my replacement sandwich. I ordered the burger at 1.57 as I was hungry and received the same wet burger once again. Its now 15.11 and they have still not brought my sandwich.
