Almost got harassed today

Nenu naa friend okka ammayi gsm mall ki ellam ivala. We go there usually also so it’s not anything new for us. But ivala Sri Chaitanya students had half day, so they were all also there. Inka Sri Chaitanya kids ante telisindhe ga, they think they’re so cool so sigma but they’re actually so ew. Maybe not all branches but this branch had those kids only. So me and my friend ordered and we sat. Some random guy came and dropped a chit on our table. We read it and it was some lame pickup line. Sarle lite edho okkati ani anukone lopala I saw some guy filming me with his phone. I thought he was just watching reels or smtg but then some random girl came up to me and told me that he was actually filming me. Asal Nak em cheyyalo ardham kaale. There were no security guards there also. So as we were getting up and leaving to sit inside one of the outlets, I could see the guy fastly walking toward us. After we went inside the store also we could see the roam around right outside and taking pictures. I was genuinely so scared. That same girl later told us that her and her friends ask that guy why they were filming us and apparently he said we’re “friends” and that we consented to him filming us. I was actually so pissed. We wanted to go confront him but vallu okka 10 people unnaru and they all looked older also, and we were just 2. Sare edhi aythe adhi ani elli we’ll sort out ane lopu they left. This shit will always scare me. Plus I genuinely wanna know asal Enti valla mindset ani. How do they think it’s just okay to film someone without permission. And what should I have done about it? Nen chesindhi correct eh na?
