A challenging receptionist (male voice)

"Umm... who are-" The receptionist began, looking from her computer as the door squeaked open.

"Walter. Er... Mr. Schmidt." Walter's voice came from the person who just entered. "Mr. Miller in?"

"Yes, but you are clearly not-"

"My ID, riiiight." Walter muttered, trying to remember where he put it. Fishing around his new clothes, it took him more than he wanted to find it. "Here. See?" Walter asked, handing the receptionist his ID.

"You have this, but-"
"It's me. Is this enough to prove that?" Walter asked.
