In response to Mr. Mauro Cesaro:
Normally I don't get lost in polemics but, this time I'll make an exception.
It would be, first of all, to specify WHAT type of beer you and the lady drank, since you didn't do it, I'll specify: You drank two Carlo V, one red and one black in 0.33cl format.
You don't say that the foam in your glasses was present but, above the specific mark of the 0.33 format I don't know if you are used to drinking beer without foam in which case, it would be a good idea to warn the innkeeper before pouring.
When you entered, in addition to having welcomed you with kindness, you were surrounded by 3 blackboards (I repeat, blackboards and not mini menus) that reported exactly the types of beers served (draught and/or bottle) and the relative prices, all written in large and colored characters so, you could be aware of the prices right away and decide whether to stay or go.
I owed them that much to protect my correctness and transparency, things for which I have been spending myself daily for nine years.
Kindness.
