‘Don’t Compliment My Man In Front Of Me!’ Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - 'Not IN FRONT OF ME!' Me and my man were out and about and ran into someone he knew and she straight up said "Hey..DAMN Your looking good" to my man. Now, yes he recently has been working out and everything but I felt that was TACKY and wrong for what she did. He said she was just throwing out a compliment...Well, that's cool but NOT IN FRONT OF ME...right?
