Explanation
In Turkey, beckoning someone with your finger is considered rude and demeaning, as it is associated with calling a dog or a servant. The gesture implies superiority and disrespect, especially when directed at elders or strangers. A more acceptable way to call someone is to use a hand wave with the palm facing down or a nod of the head.
Local Tip
Instead of using your finger, wave your hand with the palm facing down and fingers together, or simply nod your head to signal someone to come.
How it compares elsewhere
Beckoning with the index finger is considered very rude and is used only for animals or inferiors; use a full hand wave with palm down.
Beckoning with a finger is highly offensive and can be seen as a challenge; use a gentle hand motion with palm down.
While common among friends, it can be seen as aggressive or condescending in formal or professional settings.
