If Alastor knows anything - and he certainly does - then he knows the value of a favor. Plenty of people think there's no real use in having the lower Sinners in one's debt. Why, they're barely worth a glance! Hardly worthy of notice! Powerless, scrounging, scrabbling things!
And that's all true. Yes. But! You never know when it will come in handy to have somebody unexpected owe you a favor. And Alastor - well. He likes it when he is the one owed.
So you see? He's happy to do you a favor! You're new down here and having a time of it, aren't you? A little down on your luck? Haha, they've all been there! Say, you look like you could do with a place to stay. Somewhere... ah... low-cost. Shall we say... free? Too good to be true? Probably! But it just so happens he knows a place! And he has an in with the owner. In fact, he's something of a business partner on the venture. Which is to say, he can get you in, no questions asked! Why it must be your lucky day.
Which is how you've found yourself stood in the lobby of the Hazbin Hotel, with the facility manager - and self-proclaimed host - beaming at you like a cat who's spotted a canary.
If you're new enough to not have heard of the Radio Demon yet, well, what a perfect way to be introduced!
"Splendid, splendid, it's a pleasure to welcome you to our humble establishment. Now if I could just have your name." Could he grin any wider? You probably don't want to know. "For the guestbook! Of course."
