Alien 4/5" Tourist Beach Life.

Went to the beach early morning 5 a.m. waited at the bottom of the stairs until all the tourists came and ask them how they would feel if I flew my drone over them or near them. Believe it or not they were all excited to see it so I flew it. Yes I did get permission from everybody on a small Beach. And if new people came my spotter would tell tgem whats going on, Had to stop after 4 packs because of a local, He said ths drone was bothering his dog from 2 miles away, I didnt argue with him because dogs have amazing hearing, Could be true or he just dislikes drones so i left, What would have you guys said to him? I also got permision from the park ranger at the booth before you get in.
