What it stood for, I have no idea! But WFLA milkshakes were new in about 1983/84, I remember this because I had first started secondary school and used to pick a carton up at lunch time. It came in choc/mint flavour, rum and raisin and coffee! The tetrapak carton was kinda abstract and...well...that 80's 'art', that us girls used to hang up in our bedrooms, that you would buy from those knick-knack shops that were all the rage at the time! If I remember rightly, the slogan for WFLA was "No fizz. No cans. No lobster." Just as abstract as the name.
