-Returning or exchanging an item, even if it is flawed is uncommon in Italian stores.
-When shopping for clothes, take note that many stores will not allow one to try on shirts and blouses.

-Sunbathing topless is common on beaches in northern and central Italy, however it will most likely lead to stares and catcalls when done in the more conservative and traditional south.
-While Italy is very hospitable, keeping kids entertained can sometimes be tough. Hotels often don't have pools or videogames, while virtually nothing on the radio or television is in English.
