Explanation
In Spain, beckoning someone with a curled index finger is considered rude and condescending, as it is typically used to call animals or children. This gesture is seen as disrespectful to adults, implying a lack of equality or dignity. A more polite approach is to use an open hand with the palm facing down and fingers together, moving them toward you.
Local Tip
Instead, gesture with your whole hand, palm down, and wave your fingers toward you in a scooping motion.
How it compares elsewhere
Beckoning with the index finger is considered very rude and is used only for animals; use a palm-down wave instead.
This gesture is extremely offensive and can even lead to legal trouble; it is reserved for calling dogs.
While not as offensive as in Spain, it can be seen as overly familiar or dismissive; a polite verbal call is preferred.
