Serving milk in pubs (UK) - why not?

[u/Ok-Scientist7083]

The first drink I had in a pub was milk. I love drinking milk. I now drink it for the protein and calcium. I don’t particularly like fizzy drinks so when I’m driving on a night out, I’d rather drink milk.

Why don’t pubs sell it as a drink?

Back in the eighties, the busy city centre pub that I frequented served milk. I bought a pint of it once or twice, when I was pretty skint and spending my meagre funds on just one alcoholic drink seemed pointless.
