There was a place down there that I visited to see one of my trainees who worked there, some sort of Customs place for wine merchants.
I can't remember the name of it now, I just remember it being packed to the rafters with alcohol ☺️
I also had trainees in the offices at P&O. Christ was that a scary place to drive through!
All that area back in the 90s looked abandoned and desolate, hardly a soul anywhere yet it must have been packed with workers just a few decades earlier.
