While we were at the "grandmother" and "grandfather" rocks at Koh Sumui, there was a Thai-falang couple with her teenage son. They were up at the grandfather rock for quite a long time. The area up there was small, basically preventing anyone else from going up there. Additionally, it meant that they were in every else's shot, as they were right in front of the grandfather rock.
It wasn't something that I was going to complain about, because I knew I could easily crop them out and I didn't actually care if I went up to the rock itself. Still, I'm not a big fan of people monopolizing a spot, particularly when they are spending a good deal of it reviewing the photos (most likely poorly composed :D) that they just took.
When we were about to head out, the teen boy had come down off the rocks and told Tim that the view up their was great, and that we should go up. Here is the synopsis of the conversation:
Boy: You should go up there, the view is great. You can get lots of great photos.
Tim: Yes, I know, but people stay up there so long and monopolize the spot. That would let other people enjoy it.
Boy: Wait, my mom is up there still.
Tim: Yes, I know. (smiles)
Boy (screaming to mom): They are complaining about you staying up their so long.
I was a little distance away from Tim, and didn't realize the conversation took place until we were back in the car. If the guy had been a complete ass and confronted me about complaining, I would have had no idea what he was talking about.
