For the majority of my life, I worked in hot summer climates(Florida and Texas), and always had access to free water to rehydrate.

I believe the USPS does the same.

Yes, access to free water in the stations.

Not so useful when you run out on the street; when I got done with my routes, I’d take water to carriers I’d see on the street on my way home. New employees are the worst - they think a 6 pack of water bottles is enough, or their little Igloo cooler will keep that water cool.

I never personally needed the bottles of water that people would leave in mailboxes for carriers (often starting out frozen but just cool when I got to their boxes), but I always took them to give to another carrier.
