In the 60's, I used to play league darts in Byker, Newcastle. In one pub they used to pass around ham shanks with a price sticker on. If you wanted it, you looked up, and someone would nod to you and the sale was done. In another, a Dulux ? colour chard would be circulating, and you chose your paint, and the guy would approach you. The paint would be delivered same place next week, just as long as that colour was being painted in the ships that week in the Tyne Shipyards. In the pub I played for, you would see a puppy on a long string and a brown label with a price on it's collar. If you wanted it, you tugged the string and the bloke on the other end came over and completed the deal for your new puppy. All this happened with the 'nice girls' on the bar high stools, with stickers on the soles of their high heels.
Happy Days.
