In defense of this diner, I must point out that 1) he's trying, 2) most of the really bad things I've cleaned up were done by the prior tenant, and 3) this very busy place is actually kept quite clean. Not bad, when you consider that most, if not all, of the folks that work there grew up in mud huts, and everyone's english vocabulary, combined, might be enough to converse at a first-grade level!
So how did I fix this? I removed the receptacle that you see, replacing it with a "Bell" extension and blank plate. I ran a length of pipe (with mineralacs) to the end of the sink, where I surface-mounted a "Bell" box.
Placing a 20 amp receptacle was not a problem; not only was it a 20 amp circuit, this is the only outlet on the circuit (as best I could tell).
With the receptacle moved, the radio (of necessity) was also moved to the end of the sink area.
