If an Italian speaking English to you sounds pretty much EXACTLY LIKE the bartender from The Three Amigos:
then that person is from either Bergamo or Brescia. But DO NOT, under any circumstances try to guess which of the two they are from. The two towns walking distance apart not only hate each other, but are convinced that their own town is both vastly different and radically superior than the other. Instead of being flattered that you have identified a place in walking distance from their small hometown, if you get it wrong they will hate you forever.
I'm an American living in Italy and making gross generalizations about it.
