Reverse Eater Fetish
The reversed version of an eater fetish. The person with this fetish likes watching people eat, but often won't find it pleasurable if they aren't the one who got them the food. They didn't have to make the food, they just have to be the ones who got it for them. They also usually enjoy the experience more if the person (or people) eating thank them afterwards, no matter how difficult the food was to get or make.
Person 1: John is so weird. Every time he orders us food, he doesn't eat with us, but he just stares at us eating. And he then doesn't stop bothering us until we thank him like 6 times for it.
Person 2: Yeah, he must have a reverse eater fetish!
