Watercoolers are devices for dispensing cold (or hot) water from huge plastic bottles in a classic office. People go there to get their hydration fix, say hello to each other, and this ostensibly turns into a longer chat, as everyone keeps procrastinating.

I haven't seen an actual watercooler for the last 10 years, so they're probably becoming less common in tech companies.

Oh yeah, seen a ton of those in movies (but not in real life tho). Thanks

At least in tech companies, they seem to being replaced by taps that can dispense hot or cold, still or sparkling water, with optional flavors added.
