With help from his family name

Blue winces as he points to the cheapest available room. Even though he can afford it, it's obvious that he didn't want to spend this much.

"This one?" the receptionist confirms. Blue nods. She takes the paper away and types something into her computer. "May I have an ID so I can book the room, please?"

Blue rummages through his bag, taking a surprisingly long time to find his Pokedex. He clicks over to his Trainer ID and places it on the desk. You wince a little when you see at the bottom your name with the words "Sex ****" next to it. "This should do, right?" Blue asks. The receptionist nods and begins typing his info into the computer.

You expect to wait several minutes for her to type in all his information but only a couple seconds in she stops, her face filling with surprise. She turns back to Blue, the customer service smile returning to her face. "Oh, thank you, Mr. Oak, for being a Grandmaster Tier Rewards member."

"Me, what? That can't be right," Blue replies with shock.

"The Professor is your grandfather, is he not?" the receptionist asks. Blue nods, and she continues. "He has you listed as an authorized user on his Rewards profile. And at Grandmaster Tier, you are entitled to any available room free of charge." She pulls out a key card from under the desk and hands it and his Pokedex to him. Blue haphazardly stuffs his Pokedex back into his bag and stares at the fancy-looking key card while she continues her explanation. "The room itself is free but any add-ons are not. This includes any service or cleaning fees incurred and any room service requested. However in the Rewards account I do have instructions to bill any charges directly to your grandfather. Please enjoy your stay, Mr Oak."

With a slight bow and a gesture towards the elevators she sends you on your way. You follow Blue to the elevators, glad for your bare ass to finally be away from the lobby. The wait for the elevator feels like forever, but eventually it does finally open and the two of you step inside.
