Embarrassed a perv today...

Was in Cash & Carry today seeing what kind of meat they have, looking for pork bellies to make bacon. There was a woman, guess her to be in her early 40's. She had a very attractive daughter with her. Gess she was around 20 or so. The younger lady walked in front of me, excusing herself as she walked between a display case I was looking at and me. There was an older guy, had to be mid 60's standing next to me. He was doing the elevator eye thing as she walked by...and she caught him. He was watching her as she walked away...I said, very loudly, that the old dude was a perv and needed help. Her Mom went over and chewed the guy out. Mom walked up and hugged me, thanking me for saying something. When I was walking thru the parking lot I seen the old dude getting into his car...guessing with his wife waiting for him. Don't get me wrong I check people out. But in no way like this perv was doing.
