Front Desk Staff: "Welcome to the Kerberos Hotel. How may I help you?"

Hale Childeric: "I would like to book a reservation for two nights."

Front Desk Staff: "Sure! May I have your ID card please?"

(Hale gives his card to the staff)

Front Desk Staff: "Okay sir, here's your ID card, your key card, and your key-granting card. Please go into the Key-granting Staff right there to get your room key."

Hale Childeric: "That's... more convoluted than it should've been."

Front Desk Staff: "This is the Kerberos Hotel. We are special for implementing the Kerberos protocol, a protocol used for secure communication among computers, into a hotel."

Hale Childeric: "... But why though?"

Front Desk Staff: "Apparently it brings people in."

Hale Childeric: "... Okay... so, should I give all of these to that... uh... staff?"

Front Desk Staff: "Yes, sir. To the Key-granting Staff in front of the elevator on your back."

Hale Childeric: "Oh, okay then."

(Hale went to meet the Key-granting Staff)

Key-granting Staff: "Good afternoon sir, may I have your cards right there?"

Hale Childeric: "Here." (gives all the cards)

Key-granting Staff: "Okay sir, your room number is 8C3F, on floor 8C. Here is your room key, along with your one-time password."

Hale Childeric: "Oh okay. Thanks."
