RE: Tipping is not compulsory but necessary.

Well in most cases it might look like we are not being forced or it is from the heart but deep down we know that the only reason why we are tipping a particular person is not just for appreciation but to get better service and favours from them next time.

The line between tipping for the right reasons and for the wrong reasons kind of blur overtime. In most cases tipping start looking a lot similar to bribe.
