After Kurogiri had a quirk malfunction he ended up in Grillby's bar, hearing the Fire monster grumbling about how a 'Sans' hasn't paid his tap

Kurogiri:"Uhhh, Excuse me sir, do you know where I am, I need to get back home to young master Shigiraki"

Grillby:"You're in My bar in Snowdin, Welcome to the underground. Now little spark(you) could you get this kind fellow a drink?"
