No tipping means better business
As a person who was born and living in a country which has no tipping culture.
The tipping sucks.<p>I should have been fully informed how much should I have to pay before I purchase something or some service.
Any extra demand from agreed amount should be illegal.<p>I also don't want to waste my precious time on paying the tip for calculating tax.<p>The worker's salary is a employer's responsibility.
If the the worker become underpaid without the tipping, then the worker is underpaid by the employer.
