No, quite tropical really. It's true static doesn't build up often, but when dealing with very expensive things - it makes sense to use high impedance dissipation anyway. Is it totally necessary? Probably not.
Quite understandable, you definitely don't want to bork up an expensive repair. I happen to live on the Gulf Coast of whatever the fuck the orange turd calls it, and our general rule of thumb is that we only bother busting out the anti-static wristbands when the doorknobs and stuff start shocking you.
I've only ever seen one device in my life fail from static electric discharge, and that was because my boss was an idiot and wanted to hover over my shoulder and then point at a chip and asked what it does ๐๐คฃ
The spark doesn't have to be big enough to feel for it to cause damage. The damage doesn't always appear immediately either.
Electricity can be totally weird like that. Some chips are stupid sensitive, while others are crazy robust.
Here in South Mississippi, usually the humidity is so high that static electricity is almost non-existent, except during crazy cold weather, which isn't very common, but of course does happen occasionally.
I've actually fixed a lightning struck desktop PSU before, by just removing the full bridge rectifier, cleaning it and the main PSU board traces, and reinstalling the very same full bridge rectifier, lightning melted pins and all, and it just worked.
How? Why? I really don't know, but yeah, sometimes it takes more than a full bolt of lightning to kill something. Yet other components can be so sensitive as where if you just look at it from the wrong angle it fails.
