There are two restaurants in the village that serve limoncello.
In one, I ordered a glass after dinner. Subsequently, the owner started serving everybody else limoncello on the house. We still had to pay for ours.
In the other, I made a mistake and felt embarrassed. They insisted on serving me a limoncello. And my wife. On the house.
You can guess once where I have never gone back and where I keep coming back.
What does your limoncello on the house look like?
