OMG! I just had a meeting with a yes person. In this case, a woman. The 3 hour meeting was painful enough as long as it was. But after every sentence that anyone else finished, she said (not quietly, but rather clearly, audible to the entire room) “Oh, yes.” “Exactly.” “Yep.” “Umm hmm.” Over and over and over again. I wanted to slap her! I kept looking around the room to see if anyone else was noticing this. Maybe they’re all used to it by now.
