Explanation
In Mexico, beckoning someone with your finger, especially with the palm facing up, is seen as a gesture used for calling animals or inferiors and is considered highly disrespectful in everyday contexts. It implies a lack of respect and can be interpreted as condescending or aggressive.
Local Tip
Instead, to call someone politely, extend your hand with the palm facing down and make a gentle scooping motion with all fingers together.
How it compares elsewhere
Beckoning with a finger is considered very rude and can even be illegal; use a hand wave with palm down instead.
Beckoning with a finger is seen as demeaning; use a gentle wave with all fingers together and palm facing down.
