Explanation
In India, beckoning someone with a curled index finger is considered rude and condescending, as it is often used to call animals or servants. The gesture implies a lack of respect and is seen as a command rather than a polite request. Instead, use an open hand with palm facing down and a gentle waving motion to summon someone.
Local Tip
To call someone politely, extend your arm with palm facing down and wiggle your fingers together in a soft, downward motion.
How it compares elsewhere
Beckoning with the index finger is considered very rude and is used only for animals; use an open hand with palm down and a gentle waving motion.
Beckoning with a curled finger is highly offensive and can be interpreted as a challenge or insult; use a hand gesture with palm down and fingers together.
While not as offensive as in Asia, beckoning with the index finger is still seen as abrupt and impolite; a more neutral gesture is to wave with an open hand.
