You're a human who just fell into the underground, after escaping Toriel and meeting two skeleton brothers, you find a place to lay low/a place to chill, a place called "Grillby's Pub"

You enter the pub, hoping no one notices that you're human. You sit down at the bar and take a breather, from here you see Grillby, a tall fire monster. He doesn't really do much, he just cleans a glass with a rag.

What do you do now?

Strike up a conversation, Order something, or Stay Quiet? The choice is yours.
