A slightly more in-depth analysis:
The US government changed the rules to allow more powerful showers after Trump complained about not getting enough water to wash his hair"An Obama-era restriction on showerheads was rolled back on Tuesday, after President Donald Trump complained about showers not providing enough water to wash his hair."
"During a White House event back in July, Trump expressed a grievance with the water output of showerheads, according to Reuters."
"Trump complained that showerheads under the Obama-era rule put out too little water to do a good job."
"So what do you do? You just stand there longer or you take a shower longer? Because my hair — I don't know about you — but it has to be perfect," he said at the event."
https://www.businessinsider.com/us-rolls-back-shower-restrictions-after-trump-complained-2020-12Do you know how I know Trump is an idiot? He doesn't know that to get more water flow from your shower head, you simply unscrew the showerhead, remove the little perforated disc that has the fancy name "flow restrictor", and screw the showerhead back on. Even if he knew how, Trump would probably have a plumber come in and do it for him, and then stiff the plumber on the bill because it was such an easy fix.
That, and his hair is not, and has never been, perfect by any stretch of the imagination. A perfect comb-over is an oxymoron. And before you Trump supporters get all apoplectic about it, Biden's hair plugs aren't any better.
