Tipping etiquette and dealer appreciation can vary widely depending on cultural norms. In North America, tipping is typically expected, with amounts differing by the venue, such as casinos or restaurants. In European countries, tipping may be less expected, often rounding up the bill or leaving a smaller percentage. Some Asian countries, such as Japan, may find tipping unusual or even offensive, as service is included in the price. In regions like Australia and New Zealand, tipping is uncommon, and appreciation is shown more through respectful interaction.
