This has got to be the most stupid comment and counter-argument I read this week.

1. Metal water bottles and thermos have been around for way longer than tech bro.

2. Metal water bottles and thermos have been used by every kind of workers for more than half a century. Even fancy ones.

3. Thermos and water bottles are way cheaper than plastic bottles pack. Starts at ~$8 at wallmart https://www.walmart.com/c/kp/stainless-steel-water-bottle. So, no, it's not some fancy tech bro elite shit.

Now, bottled water has its use but if you are running a construction site you know damn well you have better and cheaper options (towable water bowsers, citerns, tanks, etc.).
