tazza grande/cappuccino etc. I've tried just about any combination in almost all European languages. Over the years I've concluded that the less I say the bigger the chance that I'll get something drinkable :)

Baristas & waiters - please don't empower the word barista by using it as if it's different than a waiter. Barista is just a waiter that's also a condescending prick that happens to have a beard.
Don't get me wrong, I don't look down on waiters, I actually like them, they are a social group that I communicate with more than any other. But when some idiot with a 4-day workshop on making coffee starts explaining to me why I should never drink coffee the way I like it

Dude you should really try our coffee that was brewed using only virgins tears without anything and only from this warmed cup that was painted by a local hippy ...

I just go psycho

Sweetener - yep, I take my coffee with it at home but I've given up on it when in the bars - it's just too painful

sempre freddo my ass - this was taken today at Cinque Terre - I can't remember which one :)
