I mean this does make sense for places where you have a client and you want them to be able to see you doing the math to some degree to give an air of transparency and encourage trust.

Exactly, this would be totally common in small mom and pop stores or at a flea market in the age before digital payments and ubiquitous phones.
The person is probably just young. Wait till they discover that rewinding something used to be literal.
And when you paused something it used to start moving more.
Wait what? I grew up on VHS tapes and... What??
Or when you split the bill at the end of the date lol
I'll see your dual screen and raise you a Casio desktop calculator.
i have five of these in my closet
This calculator looks like it comes with a hefty manual and has a following as devoted as vim users
These are pretty simple calculators, those switches on top just change how the printing happens. You can set them to print with leading decimals (eg. adding a .00 to monetary values) and alignment to make reading easier. Otherwise it's just a pretty standard calculator. Great machines, you still see them used for audits as a final hand-calculation stapled to the top of the paperwork.
This was the machine to count down registers at the end of every retail shift. Great little things. Training someone new on it was always a process though. A lot of people struggled with the concept of entering the sign/operation after the number.
Example 10+2-5 = 7 is entered into the machine as 10 [+] 2 [+] 5 [-] [* or T]. Of course most people treated it like a regular calculator and hit 10 [+] 2 [-] 5 and then scratched their heads to find the equals.
OMG this one brings back memories! My uncle had one in his shop, I loved the bzzzzt bzzzzt it made...
Make sure your spouse isn’t around to see: http://www.vintagecalculators.com/
they don't have a for sale section because this might be my christmas list
It's too hard to flip upside down when you type 58008
I have one of these! I actually use it at work too.
...what do the money detector and red buttons do?..
The money detector button illuminates a bright UV light on the side that you can use to detect fake notes.
No idea about the red button. I heard one reviewer say the word "computer" while pointing at it (all of the reviewers seem to be from the Philippines, a language that I sadly don't speak), but if found no other clues.
...i wonder if the red button has something to with sending to or clearing the public display?..
It might be just the power button I can't see a power button anywhere else on it and presumably you can turn these things off.
Based on it having two screens and a picture with a pinky extended, I imagine the money detector is useless as it will always be activated in such close proximity to Mr. Moneybags here with the fancy calculator
