So something embarrassing too happened with me today. Whose fault was it? Theirs or mine?

So even though I had a very social day today, I also had a very embarrassing day. So as you all know I am a car enthusiast and I film supercars around UB City mall and Lavelle Road of our city Bangalore in India where many people have high-end cars like Lamborghinis, Ferraris, Bentleys, G Wagons, AMGs, BMW M4, Maybachs etc. But today outside this mall in Madiwala area of our city, I saw this 90s Mercedes Benz model parked. As a car enthusiast, I immediately started filming the cars as old Mercedes is very rare in Bangalore and also many car enthusiasts would film it for real. But the most unexpected happened. Suddenly 2 guards of the mall from a distance shouted "Oyeeeeee" and literally stopped me from filming. They were clearly giving me the gesture to leave the mall area. It felt embarrassing as other people around saw it too. Idk why the guards interrupted even though I was just filming a rare classic car. I film around UB City mall all the time but no one stops me so idk why those guards had to shout oyeeeee. But yeah Madiwala is a more local neighborhood of the city where car enthusiasts don't film cars like they do in UB City which is more upscale and exotic cars are more common there compared to Madiwala so maybe thats why the guards were too protective. It felt embarrassing to get stopped and told what to do as a 25 year old adult man. Whats crazy was that their Oyeeeeee came immediately after I started filming the car. So whose fault do you feel it was? Mine or did the guards overreact?
