When a man flirts in front of his wife 👎

I met with clients today and the husband was a little flirtatious and it’s something I cannot stand when the wife is there. He was older, in his sixties. I left the meeting early and my coworker who finished the meeting just commented how the husband couldn’t keep his eyes off me. I’m mortified that a man would behave like that in front of his wife. It made me feel awful. Luckily it was a one time meeting and I’ll never have to see them again.
