This generation is not looking out for the idiots, out of any sense of altruism, lol. Rather, corporate lawyers, under pressure from insurance companies, are reacting to the swell of litigious idiots, who are winning lawsuits, because a manufacturer didn't CLEARLY state that hairdryers shouldn't be used in showers or that one shouldn't stand on the very top rung of a stepladder...or that people shouldn't parch their thirst with battery acid, lol. That's why modern documentation has all these ridiculous caveats, why modern products have all these ridiculous warning stickers plastered on them-they want to pre-emptively avoid giving idiots a pretext to sue for their idiotic actions.

Could also be to dissuade people from using the stalls for hook-ups.
I worked at a WW2 era aircraft manufacturing plant that had those types of doors. Pretty sure their motive was productivity based. Hard to take a nap when any boss can see your face. This factory also had short swingdoor urinals scattered along the walls of the production floor. Since the workforce was almost exclusively male at the time of construction, it saved a lot of the schlepping time required to get to and back from the much more distant, second story, full service washrooms.

Don't know for sure if they're actually pop culture characters or just a street artist's clever creations.

Agree. Being successful doesn't equate to being famous. There's over 2700 billionaires on Earth, all "successful", but 99% aren't household names with well-known mugs. Without that photo putting her claim immediately into context, or at least a line naming them, she's just some unknown, random 20-something, complaining that her anonymous folks had very little to do with her definition of "success", making it absolutely meaningless to most viewers.

I rate your story 11/11 on the This Is Spinal Tap scale.

Asked Google if speed limit signs are embossed, and this very sign appeared on an eBay link. Described as heavily embossed steel. So "mostly" flat, lol.
