Mug Shot

I was standing in the elevator sipping my coffee. On the way up a man and a woman got on at the 5th floor. They stood beside each other quietly for a moment, then the man said:

"Did you ever get your mug back?"
"No," replied the woman. She hesitated and then said, "But I know who took it and I don't know what to do about it." They were quiet for a minute.
"You know, I don't want to accost a colleague, but it's a one of a kind mug from Victoria."
"Oh, I see," said the man.
The woman then leaned in towards him and said very quietly, "Can you keep a secret?" She looked back at me suspiciously then cupped the man's ear with her hand and whispered something, presumably revealing to him the name of the mug-napper.
"Really," said the man. He looked back at me briefly. His smug expression said I know something you don't know, making me feel like we were little kids in grade school.

The three of us got off on the 10th floor. As I made my way to my desk, I smiled at myself, amused. What was so special about mugs? People left them lying around the office kitchen all the time. In fact, the mug I was sipping out of right then I had found in the kitchen. As I drank the last drops of coffee, I noticed the tiny white writing at the bottom of the mug that read:
Victoria BC
