I care a lot more about outcomes than whether the person I'm talking to is "real" or not. If my bill gets corrected by an AI but not a person? I'll take the AI.
Think of the classic "is 0.002 cents the same as 0.002 dollars?" call - https://verizonmath.blogspot.com/ - I just tested, and chatGPT seems to understand the difference - so maybe this would be a case where the AI is better.

I assume you meant 10c and not 0.1c.

Amazing this 20 year old blog is still up. Verizon doesn't know the difference between cents per kilobyte and dollars per kilobyte:

This reminds me of this hysterically funny customer service call to Verizon: https://www.youtube.com/watch?v=MShv_74FNWU

Your pricing page is not as clear as it could be.
When people read "$0.001 each" they sometimes understand it to be one thousandth of a cent rather than one thousandth of a dollar.
Even though you are completely correct/accurate, people find it confusing (1).
Wouldn't it be clearer to say "1 cent fore every ten uses" (or "10 calls for a cent" or "a tenth of a penny per call")?
Admittedly, your audience is semi-technical, and should parse it correctly, but why not simplify it?

It's interesting how easily people mistake orders of magnitude when they are using different units of measure simultanously -- in the article you linked, first they say:
give it a mark-up from 0.03p to 95p per half litre;
and then:
In other words, Dasani is less healthy than regular tap water, but at more than thirty times the price.
It's not thirty times the price -- it's three thousand.
It reminds me of a Verizon Math story[1].

ah, verizon and billing mistakes, name a more iconic duo.
immediately reminded me of the "verizon doesn't know dollars from cents" phone call circa 2006.

I'm guessing the same kind of people who don't understand the difference between 0.002 dollars and 0.002 cents (http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr…

Back in 2006, Verizon was similarly confused over the meaning of ".002 cents per kilobyte." http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr…

I think your friend was actually trying to tell you about this story [1] not something that actually happened to them.

Remember your units!!

0.02 cents and $0.02 are two different things. I was confused by your reply. See [1] for a very frustrating example where Verizon reps made the same mistake.

Sorry but ..
"$0.02 cents"? Do you mean "$0.02", or "2 cents" or two hundredths of one cent, or something else?
Is this Verizon writing? ( http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr… )
biot · 2012-07-09
As a counterpoint, I think in cents per minute regarding phone calls. I can translate $0.008 with a bit of thought but 0.8 cents is immediately obvious. Perhaps that would trip up people at Verizon[0] who think 0.99 cents is equal to 99 cents, but I think your units are fine as-is.

And some of them don't even understand basic arithmetic: http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr…

Only for reasonably numerate folks.
See http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr… for a related horror story (Verizon and USA, but the basic point holds - you should understand what they really mean, and logic/reason holds no relevance!)

I hate it when I do that! Obviously 25 cents. http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr…

There was a big stink a few years about about the same 0.015 "cents" with Verizon. The guy recorded his phone call, and wrote a series of blog posts about it. http://verizonmath.blogspot.com/2006/12/verizon-doesnt-know-dollars-fr…

It has to help that he's semi-famous. I remember the exact same thing happening to a Verizon customer a few years back, and it certainly took longer than 5 hours for him to get his money back.

These companies need to learn math.
