I find that pretty much most people here are quite polite.
Of course, what is considered polite in Italy is a bit different from what is considered polite in the Anglosphere.
Well, I was mostly trying to be funny, but it's true that politeness is obviously culture-dependent. For example, the queuing thing isn't really done in Italy. Sure, we vaguely form a queue when it's needed, but shifting lines is pretty much the norm, and nobody gets irate about it. Boarding and disboarding the train/bus is an exercise is dodging and footwork: tiny, old ladies are usually the deadliest at it. Good luck at getting an Italian to arrive on time for a meeting, too.
The working environment is usually more relaxed (some might say "flirty"), compared with other parts of Europe or the US. This is not considered inappropriate, or harassing (except when, well, it is). Wolf-whistling like they do in 50s' movies is considered over-the-top nowadays, but expect both men and women to flirt with you, mostly just for the fun of it.
On the other hand, you'll find that Italians often go way out of their way to help you (coming with you to make sure you don't get lost if you ask for for direction, for example).
