Tip's And Tipping Tips

I was surprized to red this article in CNN.com/travel.

The story begins with you sitting in a cafe in Tokio and preparing to "leaving a healthy 20 percent tip".
I did not know a right word for this practice but it's interesting to understand this other rule to know if you visit other countries. Here are some qoters from the article:

Tipping in Japan and many other Asian countries is simply not a way of life. In fact, it's usually regarded as a vulgar display of wealth and a disregard for the culture. The same can be true in Europe and Latin America ... though not always. And in the United States, of course, tipping is expected (and sometimes demanded).

The expectation is to tip not only big but also often, from the kid handing you a Venti coffee at Starbucks to the multiple hotel hands that rush to open doors, carry bags, and offer an escort to the hotel room. (in US)

If you're taking a taxi in Chile or New Zealand, for example, the driver won't give you the evil eye if you don't tip -- it's not expected

In many European countries, this charge averages 10 percent, but it's usually included in the price of a meal. If it is, then do as the European do, and leave a few extra coins or round up the bill... And if you're heading to Fiji, Malaysia, or South Korea, be aware that no tip is required in restaurants.

I don't know about the high cost places in Italy, but in the normal life I rarely see that somebody wants a tip.
In bar you can lieve coins to the barist or put them in a special piggy bank -you can, but it's not obligatory and nobody will say you anything if you did not do it.
In some restaurants you can find 1 euro for service in the bill, but not in all of them.
There are sooooo many bars and different pizzerias and similar now, that they are happy if they have somebody that comes to eat there.

The only place where you will be forced to give tip is the toilet. Specially those in autostrada, McDonalds and similar. If you have not coins, don't go there. In autostrada look for t in filling station, not in Autogril. And be careful, there are persons that want money for parking.

Most parkings in the cities have illegal persons that want money. It's better to pay. For you, for your car and sometimes for your life. If you have not 2-3 euro to give him for place (sometimes less) it's better if you look for other parking.
