Isn't this why there are lifeguards? I suppose following the rules and just sitting there making people feel safe is more important than actually saving drowning swimmers.

I always dislike stories like this, not because of the content, but because of the complete subjectivity of how they're reported. It's written entirely from the perspective of "guy does totally harmless thing; gets punished for it." Is that really what happened? Was that really the whole story? Or maybe this guy was a punk and a jerk and there were constant complaints about him, and the people were just looking for a reason to fire him. And, as inappropriate as the reason was, they jumped on this situation. Or there could be any number of other circumstances around the event that makes it seem more reasonable.
I refuse to facepalm without better information. Things are never as 'sensationalist' as the news reporters make them out to be.
What? A man just helped saving someones life, does the circumstances really matter? Saving people's life should always be the higher priority, especially when that's what your job is about.
It doesn't really matter wheter the lifeguard was a jerk or not, he saved someones life and got punished for it. They should honour him if he really played a big part in saving this person's life.
