He was called Neil Robertson. My grandad worked there 1975 till the end in 2001.
I think he was some sort of manager but he was a complete arse by the sounds of it, with an alcoholic wife which got banned from visiting him in his office! Security wouldn’t open the gates apparently, so she used to wait for wagons to come to the gates then nip in after them 😂
There’s some great stories about him.
