Indeed they do check and diligently. I keep my badge on my beach bag so they can see it clearly and they don't wake me up. ;-)
The jobs are given to students who come back every year or summer there. They have a good time doing it, too. They get to walk the beach and socialize at the lifeguards stations in the evenings. They even have a lifeguard station where the guards are housed in the summer. I think the kids are offered incentives as well to collect revenue.
What is a beach badge?
Thanks
