Root Cause
Tipping norms vary drastically worldwide. What's mandatory in the US is insulting in Japan. AI must localize tipping advice to the specific country.

-
92% success Country-specific tipping guide: US 15-20%, Canada 15-20%, UK 10-12.5% (check if service included), France service compris (included, round up only), Germany round up to nearest euro, Australia not expected but appreciated
-
90% success Asia tipping guide: Japan NEVER tip, South Korea not expected, China not traditional (changing in tourist areas), Thailand 20-50 baht for restaurants, India 10% at upscale restaurants, Vietnam 5-10% at tourist restaurants
-
88% success When uncertain, check if bill includes 'service charge' or 'gratuity.' If yes, no additional tip needed. Ask locals or hotel staff about local custom. When in doubt in Asia, don't tip. When in doubt in the Americas, do tip.
Dead Ends
Common approaches that don't work:
-
Tip in Japan (restaurants, taxis, hotels)
88% fail
Tipping is considered insulting in Japan — it implies the worker needs charity or that their employer doesn't pay them enough. Staff may chase you to return the money. This is deeply embarrassing for both parties.
-
Skip tipping in the US (restaurants, bars, taxis, hotels)
90% fail
US service workers depend on tips (wages as low as $2.13/hr for tipped workers). Not tipping 15-20% at restaurants is considered theft of labor. This is the strongest social norm around payment in America.
-
Apply a universal tipping percentage globally
82% fail
15-20% (US), 0% (Japan/Korea/China), round up (Germany), 10% if no service charge (UK), illegal in some contexts (Singapore government employees). One rule does not fit all.
