Seeing Cova's notice about counterfeit bills, I suggest you to check carefuly any change you're given, even coins, if you aren't familiar with the currency, especially at poorly lit places. It happened to me a few times in the past (now I check it all through) at motorway toll booths in the night, getting some foreign coins instead of liras, the same weight and size but for a fraction of actual value. I think the booth attendant got tricked before by someone else and, when he realized it, he decided to minimize his loss at someone else's expenses...
