On another job I had in the past, I did microscopic analysis of various things, one being a water sample from a public hot tub; based on that, I NEVER go in public hot tubs! Because the tubs/spas use heated water, the chlorine is rapidly depleted, resulting in microbes feasting on dead human skin (yes, that hot water causes dead skin to slough off, and unless there is also excellent filtration to go along with high chlorination, it's a recipe for microbial soup :) ). I guess working in a restaurant kitchen has the same effect on people :)
I never tested their water, but since the temperature is lower than hot tubs, it is easier to maintain the correct chlorination level, so would tend to be better (but you have the increased organic load from all those dirty butts :) )
Everyone I've known who works in water treatment has told me such disgusting stories that it almost makes me want to swear off water.

How bad are like hotel pools, usually?

You are correct on the restaurant kitchens. Not all, but some are hideous. I learned in college just how much food applebees microwaves
Horses drink water, don't be an idiot and drink horse liquid.
