Why does humidity make temperature feel hot, but restaurants use misters to cool the patrons?

I live in a town with a lot of humidity in summer. I perspire a lot, but restaurants around here have misters outdoors to “cool things down”. How does that work? How can adding more humidity make the heat more tolerable?

When moisture evaporates off your skin, it absorbs a bit of heat to do so, thus cooling you off. If the air is very humid, there is too much moisture in the air for your sweat to evaporate so you don’t get any cooling from evaporation. If it’s hot and DRY, getting mist sprayed on you cools you off because the mist that is sprayed on you then evaporates, thus cooling you. The mist is like fake sweat on your skin.

Misting you when it’s humid doesn’t help unless the mist is cool, then you get the slight cooling of the cool water, but then the moisture jus sits on your skin and makes you feel sticky.
