A man and a woman were having a quiet, romantic dinner in a well-known pub in xxxx.
They were gazing lovingly at each other and holding hands. The waitress, taking another order at a table a few steps away, suddenly noticed the woman slowly sliding down her chair and under the table, but the man stared straight ahead.
The waitress watched as the woman slid all the way down her chair and out of sight under the table. Still, the man stared straight ahead.
The waitress, thinking this behaviour a bit risqué, even in xxxx, and worried that it might offend some diners and prompt others to start doing the same, went over to the table and, tactfully, began by saying to the man "Pardon me, sir, but I think your wife just slid under the table".
The man calmly looked up at her and said, "No, she didn't. She just walked in."
