My family are in the GCC, and my parents live near the coast. Iran has not once targeted a civilian infrastructure there directly, except for specific landmarks (Burj al Arab, the Palm, etc.). Whenever Iran prepares a barrage, they usually announce it on state TV, which is then picked up by local authorities or by social media channels. All the attacks that have resulted in deaths in civilian settings are due to intercepted debris falling on civilians. If Iran wanted to destroy Dubai and kill civilians, they could've easily done that by just swarming the skies with drones and exact maximum damage - but they haven't done that. It also doesn't help their case either - most civilians in the GCC are foreign expats, and the backlash against Iran from most countries like Russia, India, China and Pakistan would be severe. Iran isn't stupid, as much as you'd want to believe that.
Civilian life in the GCC is still pretty normal, except for the downturn in business and the lack of tourists during the season. People are losing jobs and Airbnbs are turning into long-term stays. But otherwise civilian life is still pedestrian - heck, my younger brother is going to the Atlantis water park tomorrow because they offered him free tickets.
Israel is obviously a different story, being directly responsible for attacking civilian targets in Iran.
