Creepy men at Silver Beach

Me(F) and my friend(F) were sitting at silver beach yesterday at 8am and a woman with a man who was holding a camera came, they were 10 feet away from us and this woman was making a dance video I guess it was all good after half an hour later two men with speaker came near us and went towards the wall now they both are continuously oogling at this woman but it was so creepy my mind immediately went into alert mode after a while I noticed that one of the men was trying to take pictures of her and the photographer also noticed the same so he went to approach the guys to ask wtf is up and before he could say anything this man started pretending like he is taking pictures of himself. And after 10 mins I could visibly see how uncomfortable she was and both of them went near water to continue with their shoot this man was STILL staring her and now playing the song “Aaj ki raat maza husn ka aankhon se leejiye”. Why are some men like this idk man I feel so disgusted.
