Earlier quoted context omitted.
People normally pay tips for a good service. Making tips mandatory provides no incentive to provide a quality service. If the service quality drops - customers will go elsewhere.
>If the service quality drops - customers will go elsewhere. Wouldn't that be incentive to provide good service? I ask because some of the best restaurants in the world do not expect you to tip - ie. Danish restaurants Noma and Alchemist.
Europe is another story. Tipping there is not expected. And staff are probably decently paid.
