A Toy?

A woman comes up to me while I'm sitting at the registry desk this afternoon:
"Hi, can I help you?"
"Yeah, toy," she says.
"Ok, a toy. What toy?"
"Off a registry."
"Ok, what's the name?"
"Toy," she says with an attitude implying that she thinks I'm a complete idiot for asking her this.
"Oh...well, what's the first name?"
She told me.

Ok, so I'm supposed to differentiate between the last name, "Toy" and an actual toy when I work in a baby department? How am I supposed to know until you give me the first name?
Pass the common sense, please.
