Has anyone actually eaten alone at a Korean BBQ restaurant?

I see quite a few people in online communities saying they've done it, but I personally haven't met a single person—not even colleagues, acquaintances, or even my classmates' families—who has actually tried it.
I occasionally see people eating alone at buffets like QooQoo or Ashley, but if someone actually eats alone at a BBQ restaurant, I truly respect them.
First of all, it feels like the restaurant owner would try to kick you out lol
