Tipping keeps getting brought up in the papers every now and then. Singaporeans travelling abroad complain about this... We need to understand the cultural and circumstancial differences.
Countries like USA, parts of Europe etc rely on tips. It is part of the price of the meal.
In USA it is about 15%. In Europe, about 10% or at least let the person keep the small change.
I hope none of our members here are cheapos...
