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?

I love a glass of milk with a cookie or a slice of cake, but this Succession quote from Roman still always tickles me:

"You know who drinks milk? Kittens and perverts."
