That ... is actually kind of weird. I mean, public pools are by definition unsanitary so it's good that hygiene is emphasised. But they're basically paying someone to monitor butts. I don't go to public pools often but I've never seen that anywhere, I guess it might even be legally problematic?
Not legally problematic in Iceland at the very least, although yeah, awkward. Then again in Finland the showers don't have anyone monitoring because it's taken for granted that everyone washes well before going to the pools, and the Finnish sauna sections are in the shower area - and actually have a swimsuit
ban. So you know, Laufey 2045 would probably still sign that sentiment.
Be the gravel beds to rough for thy non-hobbit feet? I don't know of many sand-beach lakes, and I believe most of them are artificial.
...or Finnish, as it may be. This is what you get for spending your childhood summers by lake Näsi.
Fun fact time: Iceland's got plenty of natural sand beaches but there's at least one artificial one that was created solely for the purpose of having a white sand beach (as opposed to normal sand colour, black).
