Otherwise, leave consenting adults to themselves if they're discrete.
There is NOTHING discreet about what you are suggesting. "Oh, excuse us while we go fuck in the designated fucking place at work while y'all keep working. Be right back for the next meeting in 20 minutes."
That is the exact opposite of discreetness and discretion.
If you abuse, harass, or coerce someone, you should be shown no mercy. Otherwise, leave consenting adults to themselves if they're discrete.
