The photo below is of a pub in Wythenshawe, South Manchester in the early 70's.
My Mum who grew up down the road went in the off-licence on the left for bottles of Guinness in the 60's. The "outdoor" as it was popularly known was also where you bought draught beer to take away in jugs.
The "outdoor" at the Silver Birch is long gone, along with Wilsons Brewery in North Manchester that owned it, but the pub itself is still there and as this photo shows it's been knocked through and added to the rest of the pub as many a snug and vault were in the 70's.
I don't know of any pubs that still have an off-sales counter where you can buy bottled and draught beer to take away. I'm not sure why though – I'd certainly use one if it was available.
