Today I'm in a Wework office so there's coffee machines, an absolute disaster for a coffee addict like me.
In Italian we would call this a Espresso Doppio or simply a Caffè Doppio (when ordering a caffè in Italy, the assumption is that it's espresso).
Well, if you ask for caffè doppio in Italy be ready to get looked at as if you were hangover. Some barista might ask you if you had a long night!
Over here in the UK however, getting a double is normal.
