Bribes and tips

Tip is a form of bribe, giving something expecting a better service. What is given, being, after the service, will not change its form. In case of tips it is the general understanding that it should be given in the end of the service. There is a general understanding even how much should be given. But this is a pressure for most people who are unfamiliar of the process. They will always start to think whether they overpaid or underpaid. It is really comfortable to live in a country like Japan. There no-one gives tips nor expects a tip.
I feel all countries that promotes foreigners in their countries should aim to phase out giving tips.Because they will be the ones who are unfamiliar in giving tips. Not bold enough to offend locals, usually they over pay, living in unfamiliar circumstances.
This is a pressure on foreigners, so if you want to promote tourism tips are not a good attribute. It will be difficult to do away of it immediately because it will affect directly livelihood of some people.
So take action to discourage it and have alternative forms like adding it to the cost and give a commission to the servers.
