1. What does it mean?
팬서비스 describes audience-pleasing gestures or interactions, such as waving, responding to a sign, or sharing an extra behind-the-scenes moment. In idol conversation it usually concerns the relationship between an artist and their supporters.

2. The nuance
It is not an entitlement to physical contact, private access, or personal attention. This usage is broader than the sexualized meaning fanservice can have in English anime discussion.
3. Examples
“마지막에 손을 흔들어 준 팬서비스가 기억나.”
I remember the fan-pleasing wave at the end.
“팬서비스가 좋았지만 촬영 규칙은 지켰어.”
The fan interactions were great, but I still respected the filming rules.
