Where Are You?

A wife is having trouble finding her husband in a large shopping mall, so she calls him on his cell phone and asks where he is.
He answers the phone and asks her, "Do you remember that jewelry store where you saw that expensive diamond necklace in the window that I couldn't afford, about five years ago?"
Her heart starts pounding like crazy, knowing that her birthday is next week. "Yes!" she replies, with expectation.
"Okay, so I'm in the pub next door to it!"
