In most countries, tipping is optional unless a service charge is included. We clearly mark cases where it's expected or already added.

They're based on local customs and traveler feedback, not strict laws. Always check the bill, as some places include a service charge.

'Standard' reflects what most people leave. 'Exceptional' applies when the service clearly goes beyond expectations.

Labels summarize how tipping is commonly perceived in each country: • No tipping — tipping is uncommon or discouraged. • Not expected — tipping isn't standard, but may happen occasionally. • Rounding common — rounding up the bill is typical. • Customary — tipping is common, but flexible. • Expected — tipping is generally expected in common service situations. These labels reflect social norms, not legal rules.
