Business was exceedingly slow all day (fuck you very much, NFL), so we all had plenty of time to observe a very odd table that came in today. Couple A and Couple B came in at different times and were seen introducing themselves to each other; they clearly didn't know each other. At first, they just sat with the people they came with, and talked and ate. Then it got weird.
Wife A was holding hands across the table with Husband B, as was Wife B with Husband A. A few minutes later, the wives were holding hands across the table, and the husbands had their arms around the wives.
Then the wives went to the bathroom, and when they came back they sat down with the opposite husband of the one they came with. So it ended up with husband A holding wife B, and vice-versa, for a while after their ate. And there was more cross-table hand holding.
They were there for hours, chatting and swapping who they were cuddling with. We all came to the conclusion that they were swingers meeting potential sex partners! At least it livened up the night.
