Many retail places don't accept cash anymore.

But money is legal tender! It is the most basic legal tender.

Legal tender BEGINS with cash.

If I went somewhere and they refused my cash (my payment), I would walk away with the item.
This would be legal unless they had it posted big somewhere that cash sales were not an option.

In that case, you're shoplifting.

That is sort of scary. A vernier is not hard to read. It is basically simplicity itself, you just have to understand it. The girl with the slide rule I had told me "Thank God for calculators!" When I was in school, a calculator would have gotten you flunked. It was paper and pencil or slide rule.

What if these kids HAD to use a vernier? What if there was no "digital readout?"

When I took calc, the instructor said they had dumbed it down a little because too few were passing, so, are people getting stupider, or is technology just making people lazy?

I shudder to think what AI will do to people's learning over the next 25 years--- when you depend on AI to think for you, you don't bother to learn.

Tech is making people lazy.....
They know they can get the answer another way....

Carpenters used to have to be good at right triangle trigonometry.... Now all they need to calculate the length of a stair spine is a handheld.

It is a shame, but I've encountered one of these places in Spokane. The establishment is in the seedier part of town (doesn't leave much in Spokane) and they had apparently been robbed a few times. I ordered a beverage and reached for my wallet when I was told they preferred plastic---they would take cash if that was all I had but preferred not. I paid for my beverage WITH CASH, drank it and promptly left. It the place is so insecure, it is not safe enough for me to bring my family and friends.

No, they refused payment. Any place that does retail, cash sales are /implied/.

In retail, cash is implied and credit cards and stuff if advertised on the store window are offered as /alternative/ payment methods.

Years ago I went to a chinese restaurant. When it came time to pay, they had already cashed out their register for the night and would not accept my credit card.

They advertised taking the card on their door.

I called VISA and they told me that in that case, the store had refused payment, they were obligated to take the VISA card if they advertised taking it, and their refusal to take the card amounted to a refusal to take payment leaving me free and clear to just leave, and it amounted to a breech of contract with VISA.

A month later I went by the place and the restaurant was closed, done, boarded up.

Wow! Real brain buster there. Can't build a house without simple trig.

Even the scarecrow on Oz knew the Pythagorean formula...

And his head was full of straw.

Scary thing is that it really is just simple arithmetic, a few radicals, not even algebra really.

Well, I can sort of understand it if they are getting robbed all the time. That is the exception to the cash rule. But they still took cash.

Cash is still way better than NO SALE.

LOL, I remember the first time I figured the length of a slope using rise and run--I was amazed how easy. Reminded me of the first time I used a chain saw. The boss came back after four hours and asked why I had only cut 1/4" into one log. I was confused. He asked if there was something wrong with the saw and cranked it up. Scared the hell out of me, WHAT WAS THAT NOISE? jk

BWAHAHAH

Yeah, I think their clientele had quite a number of shady characters that didn't have plastic. I have a CC that I use for fuel purchases simply for convenience, but I firmly believe that CASH IS KING.

Of course, if you are really determined, you can even build a house without trig.

The hypotenuse can be spit-balled with other dirty and rough estimate methods.

I learned on a slide rule. Then simple calculators came along. Then scientific calculators. I was lucky, I graduated from college in 1976, and my math was mostly done by hand, with paper and pencil. Many people can "do" math because of calculators without really understanding what they are doing.

That will probably hurt us...bad.

The first calculator I ever saw was the size of a shoe box and in a glass case in the university book store. Cost more than $800. No, they wouldn't take it out for you to look at. I had to stick with my old used slide rule that cost $5.00 at an on campus garage sale.

I can do it still, for now, but I just google it usually because why the hell not

The 1972 SAT math score was the highest. "score high or die"....get drafted and sent to VN. Motivation.

In 2016 they redesigned it to make it easier.

I took mine in 1972.

 

[Concerned American]

I took mine in 1972.

If I had taken that route, I probably would have taken it in 1969, but I joined a bunch of other misguided children and visited southeast Asia.

You keep doing that ya hear.

I think I'll pass on hiring that contractor.

Wow, can't read a tape measure? Can't tell quarters from eighths, and sixteenths?

How the **** did they ever make it to the 4th grade?

They should try reading a vernier micrometer.

Lots of people out there cannot even break down an inch. Ask them to point out where is 10/16 or what’s another way of saying 6/8. You’d be shocked.

Another shocker is if you tell them a big circle has 360 degrees and a tiny circle has the same 360 degrees. They look at you as if you are speaking a foreign language.

I didn't plan it. It was the restaurant's doing.

I can't help it if they cash out their register while still open for business then don't want my CC.
