The best.

I took him to his room on my first or second day working at the hotel and I was really nervous. In the elevator on the way up to his room, a lady asked her to wish her son (a baby?) happy birthday. He instantly broke into song and made the whole PACKED elevator sing happy birthday to the baby. He was genuinely nice and listened to what you had to say as a person. He was calming on my first day too. Also a great tipper.
