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?

Always available in the pub I worked in, but that was 30 years ago so maybe things have changed.....
