Interesting adjective, vitriolic. I like it. While I worked, one of my employees told me I had a look that rendered mute and causes people to want to sit down. I thought that was high praise to be able to silence and park an imbecile mouthing off with one good look over my reading glasses.
But back to vitriolic. Derived from the french word vitriol, relating to sulphuric acid. When it was discovered in the Middles Ages, it was thought to be a universal solvent, until they realized that gold didn't react with it. Sulphuric acid (H2SO4), aka battery acid, is a mild compound compared to the aqua regia my system produces when I'm pushed beyond my easily attained limit. I am, by nature a placid person who doesn't suffer fools gladly. I admit it willingly. When aqua regia (HNO3+3HCL) starts oozinging out of my ears and eats away at my shirt's shoulders, vitriol will look like sweet tea compared to that stuff. Aqua regia can dissolve even non-reactive noble metals like gold. Customer disservice people have a way of making me turn aquaregian (if such a word existed). I'm too-left brained to accept explanations like "That's what we call a true false". I was told that today: a true false. It baffles the mind (at least mine). It's like taking a brand-new car to the dealership and be told that it's experiencing a normal problem. It's brand-new, 18 miles on the odometer and it already has a normal problem requiring a tow truck. Why is that concept not normal? If you know about it, how about fixing it BEFORE it leaves the dealership? Customer disservice people have that effect on me; sorry.
Take care, everyone.
