When I worked at McDonnell Douglas in the late '80s, there were these two married engineers - let's call them 'Cliff' and 'Karen' - who would 'sneak' out to Cliff's van just about every day at lunch hour for a nooner. It was pretty much an open secret among the group.
Sorry, I forgot to mention that they weren't actually married to each other.
It's a good thing they didn't go to a park for their trysts, because somebody would eventually have planned a group outing, like this one in Japan:
It's a tradition for Japanese to gather under the cherry blossoms [when they are in bloom, like they are at this time of year] and sing, dance and otherwise make merry.

"Our company maintains a strict ban on workplace fraternization between the sexes. One day, the boss suddenly upped and offered to take us all out flower-viewing. We'd all taken a toast when the boss said, 'Now I'll show you the real reason for why I brought you all here today,' and pointed off toward a secluded corner of the park. When I took a really good look, I realized the boss was pointing at one of my co-workers, who was having his own private hanami with one of the girls from the office. The boss turned back to us and said: 'That pair have broken company rules and I wanted you lot to be here to witness it all,'" a retail company worker tells Shukan Post. "The boss was really pleased with himself and got stuck right into the booze. He eventually went over and caught the young lovers 'red-handed.' The girl was eventually transferred off to the boondocks and the relationship was over."
