Shop Question

I was thrown for a loop today when I got the dumbest or craziest or most stupid question that I have ever gotten in the shop.

A woman who had been in the shop earlier in the day came back in with her husband. She immediately said that she was just showing her husband a few things. Fine.

They look around and she comes up to the desk and asks " Um....Are these things for sale?"
My answer, wide-eyed "yes"
"Oh, Okay" and then they walk out of the shop.

Everything has a price tag on it. Did they think I just sit in a commercial district with an open sign to show off my beautiful things?

Wow, a first in the eighteen plus years in business. I am almost speechless.
