Close to the shipyards in Greenock there were pubs that used to have products like VP wine, Lanliqu (? no idea how to spell that!!) and the like on the gantry!!!
I have also heard tell that when the whistle blew for the end of shift and men poured into the various pubs, there were trays and trays of drinks ready-poured - a
bit like when you go to a wedding or funeral these days, but multiplied!
